Construct Target Array With Multiple Sums

Explore how to use heap data structures to solve the problem of constructing a target array by repeatedly updating elements based on the sum of the array. Understand the constraints and implement a solution that returns whether the target configuration is achievable from an initial array of ones.

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 ...
