HackerRank Bitwise operators in C solution

HackerRank Bitwise operators in the c solution – In this tutorial we are going to solve the HackerRank Bitwise Operators problem in c programming with practical program code. in this problem we need to take 2 space separated integers from user and need to print the maximum values for the and, or and xor comparisons on the separate lines.

Bitwise operators in c

Using this problem we are going to learn about the bitwise operators in c programming as it uses 1 to represent the true and 0 to represent false.

HackerRank Bitwise Operators in C solution.

#include <stdio.h>
#include <string.h>
#include <math.h>
#include <stdlib.h>
//Complete the following function.


void calculate_the_maximum(int n, int k) {
    int maxAnd = 0;
    int maxOr = 0;
    int maxXor = 0;

    for (int i=1; i<=n; i++) {
        for (int j=i+1; j<=n; j++) {
            if (((i&j) > maxAnd) && ((i&j) < k)) {
                maxAnd = i&j;
            }
            if (((i|j) > maxOr) && ((i|j) < k)) {
                maxOr = i|j;
            }
            if (((i^j) > maxXor) && ((i^j) < k)) {
                maxXor = i^j;
            }
        }
    }

    printf("%d\n%d\n%d\n", maxAnd, maxOr, maxXor);
}

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

Second solution

#include <stdio.h>
#include <string.h>
#include <math.h>
#include <stdlib.h>
//Complete the following function.

void calculate_the_maximum(int n, int k) {
    //Write your code here.
    int max_and = 0, max_or = 0, max_xor = 0;
    int v_and = 0, v_or = 0, v_xor = 0;
    for (int i=1; i<=n; i++) {
        for (int j=i+1; j<=n; j++) {
            v_and = i & j;
            v_or = i | j;
            v_xor = i ^ j;
            if (v_and > max_and && v_and < k) max_and = v_and;
            if (v_or > max_or && v_or < k) max_or = v_or;
            if (v_xor > max_xor && v_xor < k) max_xor = v_xor;
        }
    }
    printf("%d\n%d\n%d\n", max_and, max_or, max_xor);
}
int main() {
    int n, k;
  
    scanf("%d %d", &n, &k);
    calculate_the_maximum(n, k);
 
    return 0;
}
