Bit Toggle

Code

#include <stdio.h>

int toggleFifthBit(int n) {
    // Write your code here
    return n ^= (1 << 5 );
}

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

Solving Approach

Toggled the 5th bit of the input integer by left shifting 1 by 5 and xoring it with input integer. 

XOR Operation with 1 always results in toggling.

0 ^ 1 = 1;

1 ^ 1 = 0;
