Construct Target Array With Multiple Sums

Hard

Given an array of integers target. From a starting array, A consisting of all 1's, you may perform the following procedure : let x be the sum of all elements currently in your array. choose index i, such that 0 <= i < target.size and set the value of A at index i to x. You may repeat this procedure as many times as needed. Return True if it is possible to construct the target array from A otherwise return False. Example 1: Input: target = [9,3,5] Output: true Explanation: Start with [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 <= target.length <= 5 * 10^4 1 <= target[i] <= 10^9
