Solution: Construct Target Array With Multiple Sums
Explore an efficient method to construct a target array from an initial array of ones by using a max heap and modulo operations. Understand how working backward reduces complexity and ensures scalability in solving this dynamic problem. This lesson helps you master heap-based techniques and reverse problem-solving strategies common in coding interviews.

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...
