Bit Toggle

Code

#include <stdio.h>

int toggleFifthBit(int n) {
    // Write your code here
    return n ^= 0x20;
}

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

Solving Approach

You can just return 'n' XOR'd with a bit mask of 0x20 (0b00100000) or a value with a 1 in the 6th absolute bit position.
