Problem Statement

Planning to place many PCs in his room, Takahashi has decided to write a code that finds how many PCs he can place in his room.

You are given $H$ strings $S_1,S_2,\ldots,S_H$, each of length $W$, consisting of . and T.

Takahashi may perform the following operation any number of times (possibly zero):

• Choose integers satisfying $1\leq i \leq H$ and $1 \leq j \leq W-1$ such that the $j$-th and $(j+1)$-th characters of $S_i$ are both T. Replace the $j$-th character of $S_i$ with P, and $(j+1)$-th with C.

He tries to maximize the number of times he performs the operation. Find possible resulting $S_1,S_2,\ldots,S_H$.

Constraints

• $1\leq H \leq 100$
• $2\leq W \leq 100$
• $H$ and $W$ are integers.
• $S_i$ is a string of length $W$ consisting of . and T.

Input

The input is given from Standard Input in the following format:

$H$ $W$

$S_1$

$S_2$

$\vdots$

$S_H$

Output

Print a sequence of strings, $S_1,S_2,\ldots,S_H$, separated by newlines, possibly resulting from maximizing the number of times he performs the operation.

If multiple solutions exist, print any of them.

He can perform the operation at most once.

For example, an operation with $(i,j)=(1,1)$ makes $S_1$ PCT.
