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.
We'll cover the following...
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...
