Problem Statement for "RoyalTreasurer"

Problem Statement

Once upon a time, there was a kingdom where math was always a big problem. When the post of the royal treasurer needed to be filled, applicants were presented with the following problem:

"We have two arrays of integers, A and B. A and B each contain exactly N elements. Let's define a function S over A and B:

	S = A0*B0 + … + AN-1*BN-1
Rearrange the numbers in A in such a way that the value of S is as small as possible. You are not allowed to rearrange the numbers in B.”

The problem writers need a program to check the correctness of the applicants' answers. Given int[]s A and B, return the smallest possible value for S.

Definition

Class:
RoyalTreasurer
Method:
minimalArrangement
Parameters:
int[], int[]
Returns:
int
Method signature:
int minimalArrangement(int[] A, int[] B)
(be sure your method is public)

Constraints

  • A will contain between 1 and 50 elements, inclusive.
  • A and B will contain the same number of elements.
  • Each element of A will be between 0 and 100, inclusive.
  • Each element of B will be between 0 and 100, inclusive.

Examples

  1. {1,1,3}

    {10,30,20}

    Returns: 80

    If you move the number 3 to the beginning of A, you get the minimal possible sum.

  2. {1,1,1,6,0}

    {2,7,8,3,1}

    Returns: 18

    The best option would be to rearrange the numbers in A this way: {1,1,0,1,6}.
