Question

How to find the maximum value we can achieve by picking k elements from an array in TypeScript

Answer 1

function maxSumOfK(arr: number[], k: number): number {
    const sorted: number[] = [...arr].sort((a, b) => b - a); // descending
 
    return sorted.slice(0, k).reduce((sum, val) => sum + val, 0);
}
 
const arr: number[] = [11, 2, 4, 9, 3, 6, 5, 1];
const k = 3;
 
console.log(maxSumOfK(arr, k));
