Fast Multiplication

Given two numbers, a and b, your task is to compute the value of x = (36 * a + b div 16) mod 32 using only bitwise operations, addition, and subtraction.

Input

The input consists of two integers separated by a space, where 0 ≤ a, b ≤ 10^6.

Output

The output should be a single integer representing the value of x = (36 * a + b div 16) mod 32.
