Given a signed 32-bit integer x, return x with its digits reversed. If reversing x causes the value to go outside the signed 32-bit integer range [-231, 231 - 1], then return 0.

Assume the environment does not allow you to store 64-bit integers (signed or unsigned).

 

Example 1:

Input: x = 123

Output: 321

Example 2:

import math

def reve(x):

    if x<=((2**31)-1) and x>=(-2**31):

        temp=abs(x)

        rev=0

        while(temp>0):

            rem=temp%10

            rev=rev*10+rem

            temp=temp//10

        #print(rev)

        if rev<=((2**31)-1) and rev>=(-2**31):

                if(x<0):

                    return -rev

                else:

                    return rev

           

       

        else:

            return 0

           

           

       

   

       

num=int(input("Enter a positive or negative to reverse:"))

print(reve(num))
