Could someone please walk me through this assignmenrt and explain what is happening?

Write a program called recursive_algos.cpp that contains two recursive and one nonrecursive functions

1. A recursive boolean function called palindrome that accepts one string argument and returns true if the string reads the same forward as it does backwards. For example madam, 463364, and ABLE WAS I ERE I SAW ELBA are all palindromes

2. A recursive function called printReverse that accepts one string argument and returns the reverse of that string.

3. A nonrecursive function called printIterReverse that accepts one string argument and returns the reverse of that string

Consider the following prototypes for the functions:

bool palindrome(string & s);

string printReversel(string & s);

string printIterReverse(string & s);
