You are an expert competitive programmer. You will be given a problem statement, test case constraints and example test inputs and outputs. Please reason step by step about the solution (that must respect memory and time limits), then provide a complete implementation in python3.

Your solution must read input from standard input (cin), write output to standard output (cout).
Do not include any debug prints or additional output.

Put your final solution within a single code block:
```python
<your code here>
```

Execution time limit: 2.0 seconds

# Problem
There is a graph of $$$n$$$ rows and $$$10^6 + 2$$$ columns, where rows are numbered from $$$1$$$ to $$$n$$$ and columns from $$$0$$$ to $$$10^6 + 1$$$:

Let's denote the node in the row $$$i$$$ and column $$$j$$$ by $$$(i, j)$$$.

Initially for each $$$i$$$ the $$$i$$$-th row has exactly one obstacle — at node $$$(i, a_i)$$$. You want to move some obstacles so that you can reach node $$$(n, 10^6+1)$$$ from node $$$(1, 0)$$$ by moving through edges of this graph (you can't pass through obstacles). Moving one obstacle to an adjacent by edge free node costs $$$u$$$ or $$$v$$$ coins, as below:

- If there is an obstacle in the node $$$(i, j)$$$, you can use $$$u$$$ coins to move it to $$$(i-1, j)$$$ or $$$(i+1, j)$$$, if such node exists and if there is no obstacle in that node currently.
- If there is an obstacle in the node $$$(i, j)$$$, you can use $$$v$$$ coins to move it to $$$(i, j-1)$$$ or $$$(i, j+1)$$$, if such node exists and if there is no obstacle in that node currently.
- Note that you can't move obstacles outside the grid. For example, you can't move an obstacle from $$$(1,1)$$$ to $$$(0,1)$$$.

Refer to the picture above for a better understanding.

Now you need to calculate the minimal number of coins you need to spend to be able to reach node $$$(n, 10^6+1)$$$ from node $$$(1, 0)$$$ by moving through edges of this graph without passing through obstacles.

## Input Format
The first line contains a single integer $$$t$$$ ($$$1 \le t \le 10^4$$$) — the number of test cases.

The first line of each test case contains three integers $$$n$$$, $$$u$$$ and $$$v$$$ ($$$2 \le n \le 100$$$, $$$1 \le u, v \le 10^9$$$) — the number of rows in the graph and the numbers of coins needed to move vertically and horizontally respectively.

The second line of each test case contains $$$n$$$ integers $$$a_1, a_2, \dots, a_n$$$ ($$$1 \le a_i \le 10^6$$$) — where $$$a_i$$$ represents that the obstacle in the $$$i$$$-th row is in node $$$(i, a_i)$$$.

It's guaranteed that the sum of $$$n$$$ over all test cases doesn't exceed $$$2 \cdot 10^4$$$.

## Output Format
For each test case, output a single integer — the minimal number of coins you need to spend to be able to reach node $$$(n, 10^6+1)$$$ from node $$$(1, 0)$$$ by moving through edges of this graph without passing through obstacles.

It can be shown that under the constraints of the problem there is always a way to make such a trip possible.

## Examples
```input
3
2 3 4
2 2
2 3 4
3 2
2 4 3
3 2
```
```output
7
3
3
```

## Note
In the first sample, two obstacles are at $$$(1, 2)$$$ and $$$(2,2)$$$. You can move the obstacle on $$$(2, 2)$$$ to $$$(2, 3)$$$, then to $$$(1, 3)$$$. The total cost is $$$u+v = 7$$$ coins.

In the second sample, two obstacles are at $$$(1, 3)$$$ and $$$(2,2)$$$. You can move the obstacle on $$$(1, 3)$$$ to $$$(2, 3)$$$. The cost is $$$u = 3$$$ coins.

Now solve the problem and return the code.
