Ikea

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 with which table. Therefore, for each table, output whether its price tag is to its left (L) or right (R).

The input consists of a single integer $n$, followed by a string of length $2n$. The string consists of the characters '#' (price tag) or 'T' (table). It is guaranteed that there is a unique valid allocation of tables to adjacent price tags.
