Two player X and Y are playing a game in which there are pots of gold arranged in a line, each containing some gold coins. They get alternating turns in which the player can pick a pot from one of the ends of the line. The winner is the player who has a higher number of coins at the end. The objective is to maximize the number of coins collected by X, assuming Y also plays optimally. You are required to complete the method **maxCoins** which returns an integer denoting the max coins X could get while playing the game. You may assume that X starts the game.

**Input:**

The first line of input contains an integer T denoting the no of test cases. Then T test cases follow. Each test case contains an integer denoting the no of gold pots. Then in the next line are N space separated values denoting the values (A[]) of gold coins in each pot.

**Output:**

For each test case in a new line print the maximum amount of money X can collect.

**Constraints:**

1<=T<=100

1<=N<=100

1<=A[]<=1000
