Find Whether Given String is palindrome or Not.

Objective : Write an algorithm to find Whether Given String is palindrome or Not.

Input:  A String,

Output: true or false on whether string is palindrome or not

Approach:

  • Use recursive approach
  • Compare first and last characters if they are not same- return false
  • If they are same make, remove the first and last characters and make a recursive call. 

Example:

Jain niaJ => compare ‘J’ with ‘J’ =>returns true

ain nia => compare ‘a’ with ‘a’ =>returns true

in ni => compare ‘i’ with ‘i’ =>returns true

n n => compare ‘n’ with ‘n’ =>returns true

string length <2 => returns true

Code:


Is Sumit Palindrome ??? :false
Is SumuS Palindrome ??? :true
Is ABCDEFGHGFEDCBA Palindrome ??? :true
Is Jain niaJ Palindrome ??? :true
Is SumuaS Palindrome ??? :false
