Construct Target Array from Ones | JavaScript Greedy + Max Heap Solution | LeetCode Coding Interview

Learn how to determine if a target array can be constructed from an array of ones using a reverse greedy + max heap approach in JavaScript. This LeetCode problem tests your understanding of greedy algorithms and heap manipulation.

🔹 Problem: Given target array, check if it can be built from [1,1,...,1]
🔹 Approach: Work backwards using max heap
🔹 Time Complexity: O(n log n)
🔹 Space Complexity: O(n)

Example:

Input: target = [9,3,5] → Output: true Input: target = [1,1,1,2] → Output: false
