Padaeng Studies Hard as a Middle Schooler

Padaeng, a middle school student, has too much to do and finds her studies hard, so her mind is always scattered. Today her teacher gave her the dreadful assignment of solving addition problems.

Padaeng finished the assignment somehow, but grading it is a huge chore. So she wants to write a program that reads her assignment and grades it automatically. Help Padaeng!

The paragraphs below describe the requirements in detail. For an intuitive explanation, see the sample input and sample output.

Padaeng's assignment paper is a matrix of size $3N \times 8M$. Problems are written on the paper, and each problem takes up 3 rows and 8 columns. The problems are arranged in $N$ rows and $M$ columns, forming a sheet of $N \times M$ problems in total. Each $3 \times 8$ area consists of a body and margin. The body is a string of length 5 or 6 written horizontally. It always starts at row 2, column 2 of the given $3 \times 8$ matrix. The body is always an equation of the form $a + b = c$. $a$ and $b$ are single-digit numbers, and $c$ is a one-digit or two-digit number. Any of $a$, $b$, or $c$ may be 0. However, if $c$ has two digits, its tens digit is not 0. The margin is always given as the character . .

Padaeng's assignment is graded as follows. For each problem, the following procedure is carried out. If the equation in the body is correct, fill every element of the margin that is adjacent to the body, up, down, left, or right, with the character *. If the equation is wrong, fill the elements at row 3, column 2, row 2, column 3, and row 1, column 4 of the matrix containing the problem with the characters / .

The first line contains two integers $N$ and $M$, separated by a space, which give the size of the paper. $(1 \leq N, M \leq 70)$

From the second line onward, $3N$ lines give the matrix that represents Padaeng's sheet, as strings. Each line has length $8M$.

Print $3N$ strings of length $8M$ that show the result of grading Padaeng's test sheet.
