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>
```

# Problem
There is a frog staying to the left of the string $$$s = s_1 s_2 \ldots s_n$$$ consisting of $$$n$$$ characters (to be more precise, the frog initially stays at the cell $$$0$$$). Each character of $$$s$$$ is either 'L' or 'R'. It means that if the frog is staying at the $$$i$$$-th cell and the $$$i$$$-th character is 'L', the frog can jump only to the left. If the frog is staying at the $$$i$$$-th cell and the $$$i$$$-th character is 'R', the frog can jump only to the right. The frog can jump only to the right from the cell $$$0$$$.

Note that the frog can jump into the same cell twice and can perform as many jumps as it needs.

The frog wants to reach the $$$n+1$$$-th cell. The frog chooses some positive integer value $$$d$$$ before the first jump (and cannot change it later) and jumps by no more than $$$d$$$ cells at once. I.e. if the $$$i$$$-th character is 'L' then the frog can jump to any cell in a range $$$[max(0, i - d); i - 1]$$$, and if the $$$i$$$-th character is 'R' then the frog can jump to any cell in a range $$$[i + 1; min(n + 1; i + d)]$$$.

The frog doesn't want to jump far, so your task is to find the minimum possible value of $$$d$$$ such that the frog can reach the cell $$$n+1$$$ from the cell $$$0$$$ if it can jump by no more than $$$d$$$ cells at once. It is guaranteed that it is always possible to reach $$$n+1$$$ from $$$0$$$.

You have to answer $$$t$$$ independent test cases.

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

The next $$$t$$$ lines describe test cases. The $$$i$$$-th test case is described as a string $$$s$$$ consisting of at least $$$1$$$ and at most $$$2 \cdot 10^5$$$ characters 'L' and 'R'.

It is guaranteed that the sum of lengths of strings over all test cases does not exceed $$$2 \cdot 10^5$$$ ($$$\sum |s| \le 2 \cdot 10^5$$$).

## Output Format
For each test case, print the answer — the minimum possible value of $$$d$$$ such that the frog can reach the cell $$$n+1$$$ from the cell $$$0$$$ if it jumps by no more than $$$d$$$ at once.

## Examples
```input
6
LRLRRLL
L
LLR
RRRR
LLLLLL
R
```
```output
3
2
3
1
7
1
```

## Note
The picture describing the first test case of the example and one of the possible answers:

In the second test case of the example, the frog can only jump directly from $$$0$$$ to $$$n+1$$$.

In the third test case of the example, the frog can choose $$$d=3$$$, jump to the cell $$$3$$$ from the cell $$$0$$$ and then to the cell $$$4$$$ from the cell $$$3$$$.

In the fourth test case of the example, the frog can choose $$$d=1$$$ and jump $$$5$$$ times to the right.

In the fifth test case of the example, the frog can only jump directly from $$$0$$$ to $$$n+1$$$.

In the sixth test case of the example, the frog can choose $$$d=1$$$ and jump $$$2$$$ times to the right.

Now solve the problem and return the code.
