Solution: Construct Target Array With Multiple Sums
Explore an efficient algorithm to verify if a target array can be formed from an array of ones by reversing the operation using max heaps and modulo. Learn to reduce computational complexity by working backward, processing the largest element first, and handling edge cases for constructing dynamic data arrays.

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
xbe the sum of all current elements inarr.Pick an index
iand setarr[i] = x.
Your task is to return True if it’s possible to construct target from arr, otherwise return False.
Constraints:
n == target.lengthn...
