Algorithm part 4: Check if a string is palindrome or not

Hey, Guys. Today i am going to show you How you can check if a string is palindrome.

what is palindrome?

Suppose you have a string mom. Now if you reverse this string you get mom again. So this is a palindrome string.

Solution

public boolean isPalindrome(String str){ char[] arr=str.toCharArray(); int i=0; int j=arr.length-1; while(i<j){ char temp=arr[i]; arr[i]=arr[j]; arr[j]=temp; i++; j--; } return str.equals(new String(arr)); } 

Hope this helps you. Thank you ❤.
