Palindrome Number

Link

Storing the first character in variable a and the last character in b. Then we just compare them and determine if they're a palindrome.

Full Solution in Java:

public class Solution {
    public boolean isPalindrome(int x) {
        
        if(x<0){
            return false;
        }
        
        int size = (int)(Math.log(x)/Math.log(10))+1;
        
        int temp = size;
        
        for(int i=0; i< size/2; i++){
            int a = (x/(int)(Math.pow(10,temp-1)))%10;
            int b = x%10;
            x/=10;
            temp-=2;
            if(a!=b){
                return false;
            }
        }
        
        return true;
        
    }
}
