2. Bit Toggle

#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;
}

XOR with 1 toggles a bit, XOR with 0 leeps it the same. Shift a single 1 to position 5, inverting bit 5 and keeping all other bits the same.
