Indra is shopping at Ikea. They find a row of ~n~ tables, with ~n~ price tags interspersed between them. However, a dilemma awaits! Indra cannot tell which price tag corresponds to which table.

For each table, output whether its price tag is to its left (L) or right (R).

Input

The first line will contain a single integer ~n~.

The next line will contain a string of length ~2n~. The string consists of the characters '#' (Pricetag) or 'T' (Table).

One line, consisting of ~n~ characters of either 'L' or 'R'.

Constraints

For all test cases, ~1 \le n \le 10^5~.

It is guaranteed that there is a unique valid allocation of tables to their adjacent price tags.
