The min-product of an array is equal to the minimum value in the array multiplied by the array’s sum.
- For example, the array
[3,2,5]
(minimum value is2
) has a min-product of2 * (3+2+5) = 2 * 10 = 20
.
Given an array of integers nums
, return the maximum min-product of any non-empty subarray of nums
. Since the answer may be large, return it modulo 109 + 7
.
Note that the min-product should be maximized before performing the modulo operation. Testcases are generated such that the maximum min-product without modulo will fit in a 64-bit signed integer.
A subarray is a contiguous part of an array.
Example 1:
Input: nums = [1,2,3,2]
Output: 14
Explanation: The maximum min-product is achieved with the subarray [2,3,2] (minimum value is 2). 2 * (2+3+2) = 2 * 7 = 14.
Example 2:
Input: nums = [2,3,3,1,2]
Output: 18
Explanation: The maximum min-product is achieved with the subarray [3,3] (minimum value is 3). 3 * (3+3) = 3 * 6 = 18.
Example 3:
Input: nums = [3,1,5,6,4,2]
Output: 60
Explanation: The maximum min-product is achieved with the subarray [5,6,4] (minimum value is 4). 4 * (5+6+4) = 4 * 15 = 60.
Constraints:
1 <= nums.length <= 105
1 <= nums[i] <= 107
