1354 - Construct Target Array With Multiple Sums.Hard
You are given an array
target
of n integers. From a starting arrayarr
consisting ofn
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.
Return
true
if it is possible to construct thetarget
array fromarr
, otherwise, returnfalse
.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
