## Challenge Overview

### Problem Statement

For 0 <= i,j < N, you will be given wi,j. You should find a permutation of 0..N-1: {p0, p1, ..., pN-1}, such that the sum over i < j of wp_i,p_j is maximized.

Each of the weights will be selected randomly from a normal distribution with mean 0 and variance 1. The weights will be given to you as an array w, where w[i*N+j] gives wi,j (you may deduce N as sqrt(length(w))). You should return an array with N elements, specifying the permutation p.

Your score for each test case will be the sum mentioned above, divided by N*sqrt(N*log(N)-N)/100. Your overall final score will simply be the average of your individual scores.

### Definition

 Class: Permute Method: findOrder Parameters: double[] Returns: int[] Method signature: int[] findOrder(double[] w) (be sure your method is public)

### Notes

-There are 100 system tests.
-If your sum is less than 0, it will be increased to 0.

### Constraints

-N will be between 100 and 1000, with the exception of some of the examples.
-The elements representing wi,i will be 0.
-The time limit is 30 seconds, and the memory limit is 1024M.
