Set Bit

Problem Description

You are given two integers A and B. Set the A-th bit and B-th bit in 0, and return output in decimal Number System.

Note: The bit positions are 0-indexed, which means that the least significant bit (LSB) has index 0.

Problem Constraints

0 <= A <= 30
0 <= B <= 30

Input Format

First argument A is an integer.
Second argument B is an integer.

Output Format

Return an integer

Example Input

Input 1:
A = 3
B = 5

Input 2:
A = 4
B = 4

Example Output

Output 1:
40

Output 2:
16

Example Explanation

Explanation 1:
The binary expression is 101000 which is 40 in decimal.

Explanation 2:
The binary expression is 10000 which is 16 in decimal

Output
