: the empty cells should be represented as dot characters
Fox Ciel starts to learn programming. The first task is drawing a fox! However, that turns out to be too hard for a beginner, so she decides to draw a snake instead. A snake is a pattern on a n by m table. Denote c-th cell of r-th row as (r, c). The tail of the snake is located at (1, 1), then it's body extends to (1, m), then goes down 2 rows to (3, m), then goes left to (3, 1) and so on. Your task is to draw this snake for Fox Ciel: the empty cells should be represented as dot characters ('.') and the snake cells should be filled with number signs ('#'). Consider sample tests in order to understand the snake pattern. Input The only line contains two integers: n and m (3 ≤ n, m ≤ 50). n is an odd number. Output Output n lines. Each line should contain a string consisting of m characters. Do not output spaces. Sample test(s) input 3 3 output ### ..# ### input 3 4 output #### ...# #### input 5 3 output ### ..# ### #.. ### input 9 9 output ######### ........# ######### #........ ######### ........# ######### #........ #########
