Palindrome Number - Math - Easy - LeetCode - मिनी टीवी

Determine whether an integer is a palindrome. An integer is a palindrome when it reads the same backward as forward.

Example 1:

Input: 121
Output: true
Example 2:

Input: -121
Output: false
Explanation: From left to right, it reads -121. From right to left, it becomes 121-. Therefore it is not a palindrome.
Example 3:

Input: 10
Output: false
Explanation: Reads 01 from right to left. Therefore it is not a palindrome.

Could you solve it without converting the integer to a string?

public class Solution {
    public bool IsPalindrome(int x) {
        if(x<0){
            return false;
        }
        
        int temp = x;
        int rev = 0;
        while(temp>0){
            int lsd = temp%10;
            rev = rev*10+lsd;
            temp=temp/10;
        }
        
        return x==rev;
    }
}
