Check if K-th Bit is Set

Code

#include <stdio.h>

int isKthBitSet(int n, int k) {
    // Write your code here
    /*int n_n=n;
    n &= ~(1<<k);
    if(n_n == n){
        return 0;
    }
    else{
        return 1;
    } */
    return (n & (1<<k)) ? 1 : 0;

}

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

Solving Approach

Solved by copying an bit and set the nth bit and the compare with original

return (n & (1<<k)) ? 1 : 0;
