Solution: Construct Target Array With Multiple Sums
Understand how to efficiently check if a target array can be built from an initial array of ones by applying a reverse process using a max heap and modulo to reduce the largest elements. This lesson helps you master optimization techniques to solve exponential growth problems and improve algorithmic efficiency.

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.length...
