Construct Target Array With Multiple Sums

Explore how to use heaps to solve the problem of constructing a target array from an initial array of ones by repeatedly updating elements with the sum of the current array. This lesson helps you understand the logic behind the operations and implement an efficient solution.

We'll cover the following...

Statement

You are given an array target of n integers.

Starting from an array arr of size n where every element is 1, you may perform the following operation any number of times:

  • Let x be the sum of all current elements in arr.

  • Pick an index i and set arr[i] = x.

Your task is to return True if it’s possible to construct target from arr, otherwise return False.

Constraints:

  • n == target.length ...
