Solution: Construct Target Array With Multiple Sums
Explore how to solve the problem of constructing a target array from an initial array of ones by working backward with a max heap and modulo operations. Understand the algorithm's steps to efficiently reduce the problem size, avoid excessive computations, and verify whether the target array is achievable, along with analyzing its time and space complexity.

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...
