Implement function reverse_int() that takes a three-digit integer as input and returns the integer obtained by reversing its digits. For example, if the input is 123, your function should return 321. You are not allowed to use the string data type operations to do this task. Your program should simply read the input as an integer and process it as an integer using operators such as // and %. You may assume that the input integer does not end with the 0 digit

>>> reverse_int(123) 321 >>> reverse_int(908) 809
