Reverse Intrger

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).

I completed my post-graduation in 2013 in the engineering field. Engineering is the application of science and math to solve problems. Engineers figure out how things work and find practical uses for scientific discoveries. Scientists and inventors often get the credit for innovations that advance the human condition, but it is engineers who are instrumental in making those innovations available to the world. I love pet animals such as dogs, cats, etc.

Let's write code for Reverse Integer in C#.

public static int ReverseIntergr(int number)
{
    //initlize value 
    int result = 0;
    //check number negative or not
    bool IsNumberNegative = number < -1;
    if (IsNumberNegative)
    {
        number *= -1; // convert number if negative 
    }
    //iterate number when number is grater than 0 
    while (number > 0)
    {
        //assign value in result variable and add last digit of number
        result = result * 10 + number % 10;
        number /= 10;
    }
    //return the result, also check result is grater than UInt32.MaxValue
    return result > UInt32.MaxValue ? 0 : IsNumberNegative ? result * -1 : result;
}
