```python
from typing import List
class Solution:
def minimumCost(self, nums: List[int], cost: List[int], k: int) -> int:
def cost_of_subarray(start: int, end: int) -> int:
subarray_sum = sum(nums[start:end+1])
cost_sum = sum(cost[start:end+1])
return (subarray_sum + k * (end - start + 1)) * cost_sum
def dp(i: int, j: int) -> int:
if i > j:
return 0
if (i, j) in memo:
return memo[(i, j)]

for k in range(i, j):
min_cost = min(min_cost, dp(i, k) + dp(k + 1, j) + cost_of_subarray(i, k) + cost_of_subarray(k + 1, j))
memo[(i, j)] = min_cost
return min_cost
memo = {}
return dp(0, len(nums) - 1)
