1. Brute Force Approach
Step 1. We will check if number < 0 multiply by -1 for simplification
Step 2. We will reverse the string by checking condition that number lie in range on integer
Step 3. And return the reversed number

CODE

class Solution {
public int reverse(int x) {
    long reverse=0;
    int rem = 0;
    int num=x;
    if(num<0){
            num = num*(-1);
    }
    while(num > 0) {
        rem = num % 10;
        reverse = (reverse * 10) + rem;
        num = num/10;
    }
    if(reverse>Integer.MAX_VALUE || reverse<Integer.MIN_VALUE) {
        return 0;
    }
    else { 
        if(x<0){
            reverse = reverse*(-1);
        }
        return (int)reverse;
    }
}
}
