Bit Toggle

Code

#include <stdio.h>

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

    return n;
}

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

Solving Approach

Toggling a bit is done using xor operation (^). Hence to toggle 5th bit, left shift 1 by 5 and then apply xor operation with the input value.
