Answer:
Written in Python:
def insert_string_multiple_times(str1,indto,str2,count):
splitstr = str1[:indto]
for i in range(count):
splitstr+=str2
splitstr +=str1[indto:]
print(splitstr)
Explanation:
This line defines the method
def insert_string_multiple_times(str1,indto,str2,count):
In the above definition:
str1 represents the string
indto represents index to insert a new string
str2 represents the new string to insert
count represents the number of times str2 is to be inserted
This gets the substring from the beginning to indto - 1
splitstr = str1[:indto]
This performs an iterative operation
for i in range(count):
This appends str2 to the first part of the separated string
splitstr+=str2
This appends the remaining part of the separated string
splitstr +=str1[indto:]
This prints the new string
print(splitstr)

Write a program with the total change amount as an integer input, and output the change using the fewest coins, one coin type per line. The coin types are Dollars, Quarters, Dimes, Nickels, and Pennies. Use singular and plural coin names as appropriate, like 1 Penny vs. 2 Pennies. The input should be an integer, with the unit as "cents". For example, the input of 126 refers to 126 cents. 1 Dollar = 100 cents 1 Quarter = 25 cents 1 Dime = 10 cents 1 Nickel = 5 cents 1 Penny = 1 cent Ex: If the input is:
Answer:
In Python:
cents = int(input("Cents: "))
dollars = int(cents/100)
quarters = int((cents - 100*dollars)/25)
dimes = int((cents - 100*dollars- 25*quarters)/10)
nickels = int((cents - 100*dollars- 25*quarters-10*dimes)/5)
pennies = cents - 100*dollars- 25*quarters-10*dimes-5*nickels
if not(dollars == 0):
if dollars > 1:
print(str(dollars)+" dollars")
else:
print(str(dollars)+" dollar")
if not(quarters == 0):
if quarters > 1:
print(str(quarters)+" quarters")
else:
print(str(quarters)+" quarter")
if not(dimes == 0):
if dimes > 1:
print(str(dimes)+" dimes")
else:
print(str(dimes)+" dime")
if not(nickels == 0):
if nickels > 1:
print(str(nickels)+" nickels")
else:
print(str(nickels)+" nickel")
if not(pennies == 0):
if pennies > 1:
print(str(pennies)+" pennies")
else:
print(str(pennies)+" penny")
Explanation:
A prompt to input amount in cents
cents = int(input("Cents: "))
Convert cents to dollars
dollars = int(cents/100)
Convert the remaining cents to quarters
quarters = int((cents - 100*dollars)/25)
Convert the remaining cents to dimes
dimes = int((cents - 100*dollars- 25*quarters)/10)
Convert the remaining cents to nickels
nickels = int((cents - 100*dollars- 25*quarters-10*dimes)/5)
Convert the remaining cents to pennies
pennies = cents - 100*dollars- 25*quarters-10*dimes-5*nickels
This checks if dollars is not 0
if not(dollars == 0):
If greater than 1, it prints dollars (plural)
if dollars > 1:
print(str(dollars)+" dollars")
Otherwise, prints dollar (singular)
else:
print(str(dollars)+" dollar")
This checks if quarters is not 0
if not(quarters == 0):
If greater than 1, it prints quarters (plural)
if quarters > 1:
print(str(quarters)+" quarters")
Otherwise, prints quarter (singular)
else:
print(str(quarters)+" quarter")
This checks if dimes is not 0
if not(dimes == 0):
If greater than 1, it prints dimes (plural)
if dimes > 1:
print(str(dimes)+" dimes")
Otherwise, prints dime (singular)
else:
print(str(dimes)+" dime")
This checks if nickels is not 0
if not(nickels == 0):
If greater than 1, it prints nickels (plural)
if nickels > 1:
print(str(nickels)+" nickels")
Otherwise, prints nickel (singular)
else:
print(str(nickels)+" nickel")
This checks if pennies is not 0
if not(pennies == 0):
If greater than 1, it prints pennies (plural)
if pennies > 1:
print(str(pennies)+" pennies")
Otherwise, prints penny (singular)
else:
print(str(pennies)+" penny")

Package Newton’s method for approximating square roots (Case Study: Approximating Square Roots) in a function named newton. This function expects the input number as an argument and returns the estimate of its square root. The program should also include a main function that allows the user to compute the square roots of inputs from the user and python's estimate of its square roots until the enter/return key is pressed.An example of the program input and output is shown below:Enter a positive number or enter/return to quit: 2 The program's estimate is 1.4142135623746899 Python's estimate is 1.4142135623730951 Enter a positive number or enter/return to quit: 4 The program's estimate is 2.0000000929222947 Python's estimate is 2.0 Enter a positive number or enter/return to quit: 9 The program's estimate is 3.000000001396984 Python's estimate is 3.0 Enter a positive number or enter/return to quit
The python program that calculates the volume and the square of the volume is as follows
radius = float(input("Radius: "))
volume = (4.0/3.0) * (22.0/7.0) * radius**3
sqrtVolume = volume**0.5
print(f'The volume is {volume} units cubed')
print(f'The square root of that number is {sqrtVolume}')
How to write the program?The complete program written in Python where comments are used to explain each line is as follows
This gets the radius
radius = float(input("Radius: "))
#This calculates the volume
volume = (4.0/3.0) * (22.0/7.0) * radius**3
#This calculates the square root of the volume
sqrtVolume = volume**0.5
#This prints the volume
print(f'The volume is {volume} units cubed')
#This prints the square root of the volume
print(f'The square root of that number is {sqrtVolume}')
Therefore, The python program that calculates the volume and the square of the volume is as follows
radius = float(input("Radius: "))
volume = (4.0/3.0) * (22.0/7.0) * radius**3
sqrtVolume = volume**0.5

Write a program called clump that accepts an ArrayList of strings as a parameter and replaces each pair of strings with a single string that consists of the two original strings in parentheses separated by a space. If the list is of odd length, the final element is unchanged. For example, suppose that a list contains
Answer:
In Java:
public static void clump(ArrayList<String> MyList) {
for(int i = 0; i<MyList.size()-1;i++){
String newStr = "(" + MyList.get(i) + " "+ MyList.get(i + 1) + ")";
MyList.set(i, newStr);
MyList.remove(i + 1);
}
System.out.println("Updated ArrayList: " + MyList);
}
Explanation:
First, we define the method
public static void clump(ArrayList<String> MyList) {
Next, we iterate through the ArrayList
for(int i = 0; i<MyList.size()-1;i++){
This clumps/merges every other ArrayList element
String newArr = "(" + MyList.get(i) + " "+ MyList.get(i + 1) + ")";
This updates the elements of the ArrayList
MyList.set(i, newArr);
This removes ArrayList elements at odd indices (e.g. 1,3...)
MyList.remove(i + 1);
}
This prints the updated List
System.out.println("Updated ArrayList: " + MyList);
}

Write a program that calculates the occupancy rate for a hotel. The program should start by asking the user how many floors the hotel has. A for loop should then iterate once for each floor. In each iteration of the for loop, the program should ask the user for the number of rooms of the floor and how many of them are occupied. After all of the iterations are complete the program should display how many rooms the hotel has, how many of them are occupied, and the percentage of rooms that are occupied.
Answer:
In Python:
floor = int(input("Number of floors: "))
totalrooms = 0
totaloccupied = 0
for i in range(floor):
rooms = int(input("Rooms in floor "+str(i+1)+": "))
occupied = int(input("Occupied Rooms in floor "+str(i+1)+": "))
totalrooms = totalrooms + rooms
totaloccupied = totaloccupied + occupied
print("Total Rooms: "+str(totalrooms))
print("Total Occupied: "+str(totaloccupied))
print("Percentage Occupied: "+str(round(100*totaloccupied/totalrooms,2))+"%")
Explanation:
This line prompts the user for number of rooms
floor = int(input("Number of floors: "))
This line initializes totalrooms to 0
totalrooms = 0
This line initializes totaloccupied to 0
totaloccupied = 0
This iterates through the floors
for i in range(floor):
This gets the number of rooms in each floor
rooms = int(input("Rooms in floor "+str(i+1)+": "))
This gets the number of occupied rooms in each floor
occupied = int(input("Occupied Rooms in floor "+str(i+1)+": "))
This calculates the total number of rooms
totalrooms = totalrooms + rooms
This calculates the total number of occupied rooms
totaloccupied = totaloccupied + occupied
This prints the total number of rooms
print("Total Rooms: "+str(totalrooms))
This prints the total number of occupied rooms
print("Total Occupied: "+str(totaloccupied))
This prints the percentage of occupied rooms to 2 decimal places
print("Percentage Occupied: "+str(round(100*totaloccupied/totalrooms,2))+"%")

It took her 9 more months but Marina has managed to save the full $725 plus more to cover fees to pay off the pay-day loan company. However, she forgot to account for the interest that had been compounding over time. Consider it is now 275 days later, the remaining loan was $725 and the APR is 47% compounded daily.
What is the total amount that Marina must now pay in order to pay off her the loan, accounting for interest?
What is the total amount of interest paid (not including fees)?
Answer:
she loaned 750 dollars.
it took her 9 months to repay it.
it was 275 days since she took out the loan.
the interest rate was 47% per year compounded daily.
the daily interest rate would be 47% / 365 / 100 = .0012876712 per day.
this assumes 365 days in a year, which is the standard assumption that i know of.
the future value of 750 for 275 days would be based on the formula of f = p * (1 + r) ^ n
f is the future value
p is the present value
r is the interest rate per time period (days in this case)
n is the number of time periods (days in this case).
the formula becomes:
f = 750 * (1 + .0012876712) ^ 275
solve for f to get:
f = 1068.440089.
that's the future value of the loan.
it's what she owes.
the interest rate on the loan is that value minus 750 = 318.440089.
that's how much extra she needs to pay in addition to whatever fees she was charged.

Define a function roll() that takes no arguments, and returns a random integer from 1 to 6. Before proceeding further, we recommend you write a short main method to test it out and make sure it gives you the right values. Comment this main out after you are satisfied that roll() works.
Answer:
Follows are the code to this question:
#include <iostream>//defining a header file
using namespace std;
int roll()//defining a method roll
{
return 1+(rand() %5);//use return keyword that uses a rand method
}
int main()//defining main method
{
cout<<roll();//calling roll method that print is value
return 0;
}
Output:
4
Explanation:
In this code, the "roll" method is defined, that uses the rand method with the return keyword, that returns the value between 1 to 6, and in the next step, the main method is declared, that uses the print method to calls the roll method.
