1354. Construct Target Array With Multiple Sums
Hard
50 Points
Array
Heap (Priority Queue)
You are given an array target of n integers. From a starting array arr consisting of n 1's, you may perform the following procedure :
Return true if it is possible to construct the target array from arr, otherwise, return false.
Examples
Example 1
Input: target = [9,3,5]
Output: true
Explanation: Start with arr = [1, 1, 1]
[1, 1, 1], sum = 3 choose index 1
[1, 3, 1], sum = 5 choose index 2
[1, 3, 5], sum = 9 choose index 0
[9, 3, 5] Done
Example 2
Input: target = [1,1,1,2]
Output: false
Explanation: Impossible to create target array from [1,1,1,1].
Example 3
Input: target = [8,5]
Output: true
Constraints
n == target.length
1 <= n <= 5 * 104
1 <= target[i] <= 109
