Please explain each line in detail and what is happening in the code as well so that i may understand what is happening. The out put must be exactly the same as the photo below.

Please DO NOT CHANGE these files:

  PART B - Stack, 15 points Please add code to the provided code. Our program tests whether an input string is a palindrome. Our program output must be identical to this sample output A palindrome is a string of characters (a word, phrase, or sentence) that is the same regardless of whether we read it forward or backward. For example, Race car is a palindrome. So is A man, a plan, a canal: Panama. More about palindromes: http://www.palindromelist.net/. We ignore spaces [>>] Enter a string (or a ! to exit): Csc [+] Yes. "Csc" IS a palindrome! [>>] Enter a string: CSC 220 - Data Structures [-] No. "CSC 220 - Data Structure" is NOT a palindrome ! [>>] Enter a string: Ah, Satan sees Natasha! [+] Yes. "Ah, Satan sees Natasha!" IS a palindrome! [>>] Enter a string: Amy, must I jujitsu my ma? [+] Yes. "Amy, must I jujitsu my ma?" IS a palindrome! [>>] Enter a string: A man, a plan, a canal: Panama. [+] Yes. "A man, a plan, a canal: Panama." IS a palindrome! [>>] Enter a string: Are Mac 'n' Oliver evil on camera? [+] Yes. "Are Mac 'n' Oliver evil on camera?" IS a palindrome! [>>] Enter a string: ! [
