Poorly Executed Mitosis

by CodeChum Admin

A mitosis program has gone out of hand and now does abnormal cell duplication. Rather than scrapping the project, the researchers decided to observe and predict the cell duplication using a program.

Instructions:

1. In the code editor, you are provided with a main() function that asks the user for the 3 integer inputs required for this program and calls the getResult().
2. This getResult() function has the following details:
3. Return type - int
4. Name - getResult
5. Parameters
6. int - Base integer
7. int - Initial factor
8. int - Number of times to process
9. Description - this is a recursive function which implements the desired behavior explained in the problem description
10. The getResult() function is partially implemented already. Your only task is to add the correct recursive case.

Input

1. Base integer

2. Initial factor

3. Number of times to process

Output

Enter·base·integer:·3
Enter·initial·factor:·2
Enter·number·of·times·to·process:·3
Result·=·54

 I Don't Feel So Good

by CodeChum Admin

In order to preserve Spiderman's last words, Mr. Stark wants us to create a program that takes a string and output the string with each proceeding output having one less character until it outputs only one string.

Instructions:

1. In the code editor, you are provided with a main() function that asks the user for a string and passes this string and the size of this string to a function call of the function, preserveString().
2. This preserveString() function has the following description:
3. Return type - void
4. Name - preserveString
5. Parameters
6. The string
7. Length of the string
8. Description - this is a recursive function that prints the string repeatedly. Each time it prints the string, it excludes the last character of the string until only one character is left.
9. This preserveString() function has already been partially implemented. Your only task is to add the recursive case of this function.

Input

1. String to be processed

Output

Enter·string:·Hello!
Hello!
Hello
Hell
Hel
He
H

Slowly But Surely

by CodeChum Admin

In life, good things take time.

Let's make a simple program that mirrors this beautiful idea where we ask the user for two integer inputs. The first one would represent the starting number and the second one would represent the next n integers after it.

For example, if the first number inputted is 2 and the second number inputted is 3, then the output would be 3, 4, 5 because these are the next 3 integers after 2.

Instructions:

1. In the code editor, you are provided with a main() function that asks the user for two integers and calls the slowDisplay() function.
2. This slowDisplay() function is a recursive function which should perform the functionality explained in the problem description above.
3. This function is only partially implemented as it lacks a base case. Your task is to add the base case needed by this recursive function.

Input

1. Starting integer

2. Number of integers

Output

Enter·starting·integer:·2
Enter·how·many·next·integers:·3
3·4·5
