JavaScript: Find the maximum difference among all possible pairs of a given array of integers
JavaScript Basic: Exercise-93 with Solution
Write a JavaScript program to find the maximum difference among all possible pairs of a given array of integers.
Sample Solution:
JavaScript Code:
// Function to find the maximum difference between any two elements in an array
function array_max_diff(arr) {
var max_result = 0; // Initialize the variable to store the maximum difference
// Iterate through the array elements
for(var i = 0; i < arr.length; i++) {
// Iterate through other elements in the array
for(var k = 0; k !== i && k < arr.length; k++) {
var diff = Math.abs(arr[i] - arr[k]); // Calculate the absolute difference
max_result = Math.max(max_result, diff); // Update the maximum difference
}
}
return max_result; // Return the final maximum difference
}
// Example usage
console.log(array_max_diff([1, 2, 3, 8, 9])); // 8
console.log(array_max_diff([1, 2, 3, 18, 9])); // 17
console.log(array_max_diff([13, 2, 3, 8, 9])); // 11
Output:
8 17 11

Flowchart:
ES6 Version:
// Function to find the maximum difference between elements in an array
const array_max_diff = (arr) => {
let max_result = 0; // Initialize the maximum difference variable
// Iterate through the array to calculate the differences between elements
for (let i = 0; i < arr.length; i++) {
for (let k = 0; k !== i && k < arr.length; k++) {
const diff = Math.abs(arr[i] - arr[k]); // Calculate the absolute difference
max_result = Math.max(max_result, diff); // Update the maximum difference
}
}
return max_result; // Return the final maximum difference
};
// Example usage
console.log(array_max_diff([1, 2, 3, 8, 9])); // 8
console.log(array_max_diff([1, 2, 3, 18, 9])); // 17
console.log(array_max_diff([13, 2, 3, 8, 9])); // 11
