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;
}

//reg |= (1 << 5) ~ reg = reg | (1 << 5);

//8bit reg = 0001 0011

//1 << 5 = 0010 0000

//reg (0001 0011) | (1 << 5) (0010 0000)
