It is New Year's Day and people are in line for the Wonderland rollercoaster ride. Each person wears a sticker indicating their *initial* position in the queue from to . Any person can bribe the person *directly in front* of them to swap positions, but they still wear their original sticker. One person can bribe *at most two others*.

Determine the minimum number of bribes that took place to get to a given queue order. Print the number of bribes, or, if anyone has bribed more than two people, print `Too chaotic`

.

If person bribes person , the queue will look like this: . Only bribe is required. Print `1`

.

Person had to bribe people to get to the current position. Print `Too chaotic`

.

**Function Description**

Complete the function *minimumBribes* in the editor below.

**Returns**

- No value is returned. Print the minimum number of bribes necessary or
`Too chaotic`

if someone has bribed more than people.

**Input Format**

The first line contains an integer , the number of test cases.

Each of the next pairs of lines are as follows:

- The first line contains an integer , the number of people in the queue

- The second line has space-separated integers describing the final state of the queue.

**Sample Input**

```
STDIN Function
----- --------
2 t = 2
5 n = 5
2 1 5 3 4 q = [2, 1, 5, 3, 4]
5 n = 5
2 5 1 3 4 q = [2, 5, 1, 3, 4]
```

**Sample Output**

```
3
Too chaotic
```

**Explanation**

**Test Case 1**

The initial state:

After person moves one position ahead by bribing person :

Now person moves another position ahead by bribing person :

And person moves one position ahead by bribing person :

So the final state is after three bribing operations.

**Test Case 2**

No person can bribe more than two people, yet it appears person has done so. It is not possible to achieve the input state.
