Given a 32-bit signed integer, reverse digits of an integer.

ReverseInteger.cs

public class Solution {
    public int Reverse(int x) {
     
        if(x<=Int32.MinValue){
            return 0;
        }
        int temp = x;
        long rev = 0;
        temp = Math.Abs(temp);
        while(temp>0){
            int rem = temp%10;
            temp = temp/10;
            rev = rev*10 + rem;
        }
        
        if(rev>Int32.MaxValue){
            return 0;
        }
        
        if(x<0){
            rev = 0-rev;
        }
        
        if(rev<Int32.MinValue){
            return 0;
        }
        
        return Convert.ToInt32(rev);
    }
}
