Problem Description

Given an integer A.
Swap the B_th and C_th bit from right in binary representation of A.
Return the integer formed.

Problem Constraints

1 <= A < 2³⁰
1 <= B, C <= 30

Input Format

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

Output Format

Return an integer.

Example Input

Input 1:

A = 9
B = 1
C = 2

Input 2:

A = 1
B = 1
C = 3

Example Output

Output 1:

Output 2:

Example Explanation

Explanation 1:

5 -> 101
Swapping 1st and 2nd bit from right gives 110.

Explanation 2:

1 -> 001
Swapping 1st and 3rd bit from right gives 100.

NOTE: You only need to implement the given function. Do not read input, instead use the arguments to the function. Do not print the output, instead return values as specified. Still have a question? Checkout Sample Codes for more details.
