    2448 - Minimum Cost to Make Array Equal.

    Hard

    You are given two 0-indexed arrays nums and cost consisting each of n positive integers.

    You can do the following operation any number of times:

    • Increase or decrease any element of the array nums by 1.

    The cost of doing one operation on the ith element is cost[i].

    Return the minimum total cost such that all the elements of the array nums become equal.

    Example 1:

    Input: nums = [1,3,5,2], cost = [2,3,1,14]

    Output: 8

    Explanation: We can make all the elements equal to 2 in the following way:

    • Increase the 0th element one time. The cost is 2.

    • Decrease the 1st element one time. The cost is 3.

    • Decrease the 2nd element three times. The cost is 1 + 1 + 1 = 3.

    • The total cost is 2 + 3 + 3 = 8. It can be shown that we cannot make the array equal with a smaller cost.

    Example 2:

    Input: nums = [2,2,2,2,2], cost = [4,2,8,1,3]

    Output: 0

    Explanation: All the elements are already equal, so no operations are needed.

    Constraints:

    • n == nums.length == cost.length
    • 1 <= n <= 105
    • 1 <= nums[i], cost[i] <= 106
