JavaScript: Check from two given non-negative integers that whether one of the number is multiple of 7 or 11

JavaScript Basic: Exercise-46 with Solution

Write a JavaScript program to check two given non-negative integers if one (not both) is a multiple of 7 or 11.

This JavaScript program examines two non-negative integers to determine if exactly one of them, but not both, is a multiple of 7 or 11. If only one of them satisfies this condition, it returns true; otherwise, it returns false.

Visual Presentation:

JavaScript: Check from two given non-negative integers that whether one of the number is multiple of 7 or 11

Sample Solution:

JavaScript Code:

// Define a function named valCheck with parameters a and b
function valCheck(a, b) {
    // Check if the negation of the condition is true
    if (!((a % 7 == 0 || a % 11 == 0) && (b % 7 == 0 || b % 11 == 0))) {
        // Return true if either a is divisible by 7 or 11, or b is divisible by 7 or 11
        return ((a % 7 == 0 || a % 11 == 0) || (b % 7 == 0 || b % 11 == 0));
    } 
    else {
        // If the negation of the condition is false, return false
        return false;
    }
}

// Log the result of calling valCheck with the arguments 14 and 21 to the console
console.log(valCheck(14, 21));

// Log the result of calling valCheck with the arguments 14 and 20 to the console
console.log(valCheck(14, 20));

// Log the result of calling valCheck with the arguments 16 and 20 to the console
console.log(valCheck(16, 20)); 

Output:

false
true
false

Flowchart: JavaScript - Check from two given non-negative integers that whether one of the number is multiple of 7 or 11

ES6 Version:

 // Function to check if the numbers satisfy the given conditions
const valCheck = (a, b) => {
  // Checking if neither 'a' nor 'b' satisfies the condition and returning the result
  if (!((a % 7 === 0 || a % 11 === 0) && (b % 7 === 0 || b % 11 === 0))) {
    return ((a % 7 === 0 || a % 11 === 0) || (b % 7 === 0 || b % 11 === 0)); // Return true if at least one number satisfies the condition
  } else {
    return false; // Return false if both numbers satisfy the condition
  }
};

// Examples of the function usage
console.log(valCheck(14, 21)); // Output: true (Either 14 or 21 satisfy the condition)
console.log(valCheck(14, 20)); // Output: true (14 satisfies the condition)
console.log(valCheck(16, 20)); // Output: false (Neither 16 nor 20 satisfies the condition)
