Problem

You have become the camp host for ICPC Sinchon, and you notice that the contest name is misspelled on the draft promotional poster. To clarify the name for the outsourced designer, you point at the poster and say "SUAPC". Unfortunately, the designer understands it as "SWAP P C".

Puzzled, the designer pairs the first P with the first C, the second P with the second C, and so on. The designer then swaps the positions within each pair.

Characters other than P and C stay as they are, and so does any leftover P or C after the maximum number of pairs is formed. Given the original text, output the text after the designer's edit.

Input

The first line contains the length of the original string $S$ . ( $1 \leq |S| \leq 100$ )

The second line contains the string $S$ . $S$ consists only of uppercase English letters and contains no spaces.

Output

Print the string after the designer's edit on a single line.
