HackerRank Bitwise operators in the c solution

YASH PAL, 16 July 202416 July 2024

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.

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.

Solution in C programming.

#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;
}
