Construct Target Array With Multiple Sums

Explore how to use heap data structures to solve the problem of constructing a target array from an initial array of ones by repeatedly replacing elements with the sum of the array. Understand the problem requirements, constraints, and develop an approach to return whether the target array can be formed under these rules. Practice coding this solution to strengthen your skills in dynamic data manipulation and heap-based optimization.

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 ...
