Given an array nums
of positive integers. Your task is to select some subset of nums
, multiply each element by an integer and add all these
numbers. The array is said to be good if you can obtain a sum of 1
from the array by any possible subset and multiplicand.
Return True
if the array is good otherwise return False
.
Example 1:
Input: nums = [12,5,7,23]
Output: true
Explanation: Pick numbers 5 and 7.
5*3 + 7*(-2) = 1
Example 2:
Input: nums = [29,6,10]
Output: true
Explanation: Pick numbers 29, 6 and 10.
29*1 + 6*(-3) + 10*(-1) = 1
Example 3:
Input: nums = [3,6]
Output: false
Constraints:
1 <= nums.length <= 10^5
1 <= nums[i] <= 10^9
