Construct Target Array With Multiple Sums

Explore how to use heaps to solve the problem of constructing a target array starting with an array of ones where elements are repeatedly updated to the sum of the array. Learn to analyze and implement a solution that returns whether this transformation is possible, practicing dynamic data processing and problem-solving using essential data structures.

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 ...
