Bit Toggle

Code

#include <stdio.h>

int toggleFifthBit(int n) {
    return n ^ (1 << 5);
}

int main() {
    int n;
    scanf("%d", &n);
    printf("%d", toggleFifthBit(n));
    return 0;
}

Solving Approach

Bitwise XOR will set to selected bit to 0 if both the mask and the bit are 1. It will set the selected bit to 1 if only the mask is set to 1.
