Program Plan Intro
Palindrome detector
Program Plan:
- Include the required header files.
- Declare and define the necessary function prototype.
- Define the main () function.
- Declare and define the necessary variables for storing strings.
- Get the required input from the user.
- Call the method “isPalindrome ()” to validate whether the given string is a palindrome or not.
- Define the “isPalindrome ()” function
- Declare the necessary variables.
- Condition to validate whether the given length of string is “1” to return the given string is a palindrome.
- Use condition statement to validate whether the length of the string is greater than one.
- If the condition becomes true, then the given string is reversed to find whether the given string is a palindrome or not.

mplement a recursive function that returns
he exponent given the base and the result.
for example, if the base is 2 and the result is
3, then the output should be 3 because the
exponent needed for 2 to become 8 is 3 (i.e.
23 = 8)
nstructions:
1. In the code editor, you are provided
with a main() function that asks the
user for two integer inputs:
1. The first integer is the base
2. The second integer is the result
2. Furthermore, you are provided with the
getExponent() function. The details of
this function are the following:
1. Return type - int
2. Name - getExponent
3. Parameters
1. int - base
2. int - result
4. Description - this recursive function
returns the exponent
5. Your task is to add the base case and
the general case so it will work

- Instructions: 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(). This preserveString() function has the following description: Return type - void Name - preserveString Parameters The string Length of the string 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. This preserveString() function has already been partially implemented. Your only task is to add the recursive case of this function.

A string is a palindrome if it reads the same forwards or backwards. Recall that str.charAt(a) will return the character at position a in str. str.substring(a) will return the substring of str from position a to the end of str,while str.substring(a, b) will return the substring of str starting at position a and continuing to (but not including) the character at position b.

- LISP Function help please A function that generates a random day of the week, then displays a message saying that "Today is ... and tomorrow will be ...". Then use the built-in function random first to generate a number between 0 and 6 (including). The expression (random) by itself generates a random integer. You can call it with one parameter to return a value within the range from 0 to the value of the parameter-1. For example, (random 10) will return a value between 0 and 9. Next, use the number generated at the previous step to retrieve the symbol for the day of the week from the list. Use the built-in elt. Extract the symbol-name of the day first, then apply the built-in function capitalize to it. Use the result in the princ function call, and do the same thing for the next day. Make the function return true (t) instead of the last thing it evaluates, to avoid seeing the message printed more than once.arrow_forwardRecursive Multiplication Design a recursive function that accepts two arguments into the parameters x and y.

The function should return 0 if the parameter string contains only digits. Note: you may not use loops of any kind. You must use recursion to solve this problem. You can assume that the parameter string is not empty.
