JavaScript: Get the largest even number from an array of integers
JavaScript Basic: Exercise-126 with Solution
Write a JavaScript program to get the largest even number from an array of integers.
Visual Presentation:
Sample Solution:
JavaScript Code:
// Function to find the maximum even number in an array
function max_even(arra) {
// Sort the array in descending order
arra.sort((x, y) => y - x);
// Loop through the array
for (var i = 0; i < arra.length; i++) {
// Check if the current number is even
if (arra[i] % 2 == 0)
return arra[i]; // If even, return the number
}
}
// Testing the function with different arrays
console.log(max_even([20, 40, 200])); // Output: 200 (The maximum even number in the array)
console.log(max_even([20, 40, 200, 301])); // Output: 200 (The maximum even number in the array)
Output:
200 200

Flowchart:
ES6 Version:
// Function to find the maximum even number in an array
const max_even = (arra) => {
// Sort the array in descending order
arra.sort((x, y) => y - x);
// Loop through the array
for (let i = 0; i < arra.length; i++) {
// Check if the current number is even
if (arra[i] % 2 == 0)
return arra[i]; // If even, return the number
}
}
// Testing the function with different arrays
console.log(max_even([20, 40, 200])); // Output: 200 (The maximum even number in the array)
console.log(max_even([20, 40, 200, 301])); // Output: 200 (The maximum even number in the array)
