How to find all pythagorean triples (a^2 + b^2 = c^2) from an array in Node.js

Answer 1

function PrintPythagoreanTriples(arr) {
    const size = arr.length;
    
    for (let i = 0; i < size - 2; i++) {
        for (let j = i + 1; j < size - 1; j++) {
            for (let k = i + 2; k < size; k++) {
                let a = arr[i];
                let b = arr[j];
                let c = arr[k];
                if (a * a + b * b == c * c) {
                    console.log(a + " " + b + " " + c);
                }
            }
        }
    }
}

const arr = [2, 3, 4, 5, 11, 6, 7, 8, 9, 10];

PrintPythagoreanTriples(arr);
