Given a binary tree, find height of it.

1
/     \
10      39
/
5
The above tree has a height of 3.
Note: Height of empty tree is considered 0.

Input Format:
The first line of input contains T denoting the number of testcases. T testcases follow. Each testcase contains two lines of input. The first line contains number of edges. The second line contains relation between nodes.

Output Format:
For each testcase, in a new line, print the height of tree.

You don't have to take input. Complete the function height() that takes node as parameter and returns the height. The printing is done by the driver code.

Constraints:
1 <= T <= 100
1 <= Number of nodes <= 100
1 <= Data of a node <= 1000

Example:
Input:

2
2
1 2 L 1 3 R
4
10 20 L 10 30 R 20 40 L 20 60 R

Output:
2
3

Explanation:
Testcase1: The tree is
1
/      \
3       2
So, the height would be 2.
Testcase2: The tree is
10
/        \
20         30
/       \
40       60
So, height would be 3.
