1770. Maximum Score from Performing Multiplication Operations
https://leetcode.com/problems/maximum-score-from-performing-multiplication-operations
Description
You are given two integer arrays nums
and multipliers
of size n
and m
respectively, where n >= m
. The arrays are 1-indexed.
You begin with a score of 0
. You want to perform exactly m
operations. On the ith
operation (1-indexed), you will:
Choose one integer
x
from either the start or the end of the arraynums
.Add
multipliers[i] * x
to your score.Remove
x
from the arraynums
.
Return the maximum score after performing m
operations.
Example 1:
**Input:** nums = [1,2,3], multipliers = [3,2,1]
**Output:** 14
**Explanation:** An optimal solution is as follows:
- Choose from the end, [1,2,**3**], adding 3 * 3 = 9 to the score.
- Choose from the end, [1,**2**], adding 2 * 2 = 4 to the score.
- Choose from the end, [**1**], adding 1 * 1 = 1 to the score.
The total score is 9 + 4 + 1 = 14.
Example 2:
**Input:** nums = [-5,-3,-3,-2,7,1], multipliers = [-10,-5,3,4,6]
**Output:** 102
**Explanation:** An optimal solution is as follows:
- Choose from the start, [**-5**,-3,-3,-2,7,1], adding -5 * -10 = 50 to the score.
- Choose from the start, [**-3**,-3,-2,7,1], adding -3 * -5 = 15 to the score.
- Choose from the start, [**-3**,-2,7,1], adding -3 * 3 = -9 to the score.
- Choose from the end, [-2,7,**1**], adding 1 * 4 = 4 to the score.
- Choose from the end, [-2,**7**], adding 7 * 6 = 42 to the score.
The total score is 50 + 15 - 9 + 4 + 42 = 102.
Constraints:
n == nums.length
m == multipliers.length
1 <= m <= 103
m <= n <= 105
-1000 <= nums[i], multipliers[i] <= 1000
