A13838 | Palindromifier

Ringo found a string $s$ of length $n$ in his [yellow submarine](https://www.youtube.com/watch?v=m2uTFF_3MaA). The string contains only lowercase letters from the English alphabet. As Ringo and his friends love palindromes, he would like to turn the string $s$ into a palindrome by applying two types of operations to the string.

The first operation allows him to choose $i$ ( $2 \le i \le n-1$ ) and to append the substring $s_2s_3 \ldots s_i$ ( $i - 1$ characters) reversed to the front of $s$ .

The second operation allows him to choose $i$ ( $2 \le i \le n-1$ ) and to append the substring $s_i s_{i + 1}\ldots s_{n - 1}$ ( $n - i$ characters) reversed to the end of $s$ .

Note that characters in the string in this problem are indexed from $1$ .

For example suppose $s=$ abcdef. If he performs the first operation with $i=3$ then he appends cb to the front of $s$ and the result will be cbabcdef. Performing the second operation on the resulted string with $i=5$ will yield cbabcdefedc.

Your task is to help Ringo make the entire string a palindrome by applying any of the two operations (in total) at most $30$ times. The length of the resulting palindrome must not exceed $10^6$

It is guaranteed that under these constraints there always is a solution. Also note you do not have to minimize neither the number of operations applied, nor the length of the resulting string, but they have to fit into the constraints.

The only line contains the string $S$ ( $3 \le |s| \le 10^5$ ) of lowercase letters from the English alphabet.

The first line should contain $k$ ( $0\le k \le 30$ ) — the number of operations performed.

Each of the following $k$ lines should describe an operation in form L i or R i. $L$ represents the first operation, $R$ represents the second operation, $i$ represents the index chosen.

The length of the resulting palindrome must not exceed $10^6$ .
