You are playing a video-game in which your character has to cross N hurdles. Initially, your character has N energies states corresponding to each hurdle. All the hurdles have their respective heights.

Now, your character can only jump over a hurdle if its energy at that instant is greater than or equal to the hurdle's height.

When you cross a hurdle of height h, your current energy gets reduced by h. The remaining energy can rolled over for subsequent hurdles.

Also, after your character crosses a hurdle, it gets an energy boost that is equal to the position of that hurdle(1,2,3....).

So, given N, N energy states, and N hurdle heights; you need to find whether you can win the game or not. You can only win, if your character can successfully cross all the hurdles.

**Input:**

The first line of the input contains a single integer T, denoting the number of test cases. Then T test case follows. Each testcase contains three lines of input:-

The number N.

N energy states, separated by spaces.

N heights of hurdles, separated by spaces.

**Output:**

For each testcase, print "You Win!" space remaining energy if you cross all the hurdles, else print "Game Over".

**Constraints:**

1<=T<=110

1<=N<=2000

0<=A[i]<=1000

**Example:**

**Input:**

2

3

1 1 1

0 2 4

3

1 1 1

8 4 6

**Output:**

You Win! 3

Game Over

**Explanation:**

For testcase1: Your inital energy for 1st hurdle is 1. The hurdle height is 0. You can cross it. The energy 1-0=1 get rolled over to the next state. Also, you gets a boost of 1 since you crossed the first hurdle. The total energy of the next state becomes 1(rolled over)+1(boost)+1(2nd states energy)=3.Now 3>= 2, so you can cross it. The energy 3-2=1 get rolled over. Also, you get a boost of 2 since you crossed 2nd hurdle. So, the next state's total energy becomes 1(rolled over)+2(boost)+1(state's energy)=4. Now, 4>=4, so you can cross it. The remeining energy is 4-4=0 plus the boost of 3 since you crossed hurdle 3. The energy at the end is 3.

For testcase2: 1 is not greater than or equal to 8. You can't cross the first hurdle.
