1735139Add to ListShareYou are given an array target
of n integers. From a starting array arr
consisting of n
1's, you may perform the following procedure :
- let
x
be the sum of all elements currently in your array. - choose index
i
, such that0 <= i < n
and set the value ofarr
at indexi
tox
. - You may repeat this procedure as many times as needed.

array from arr
, otherwise, return false
.
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
