Bit Toggle

Code

#include <stdio.h>

int toggleFifthBit(int n) {
    // Write your code here
    int mask = 1 << 5;  // 5th bit (position 4)
    return n ^ mask; 
}

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

Solving Approach

Find the mask and XOR with the input
