CF754E Dasha and cyclic table

Dasha is fond of challenging puzzles: Rubik's Cube $ 3×3×3 $ , $ 4×4×4 $ , $ 5×5×5 $ and so on. This time she has a cyclic table of size $ n×m $ , and each cell of the table contains a lowercase English letter. Each cell has coordinates $ (i,j) $ ( $ 0

The first line contains two integers $ n $ and $ m $ ( $ 1

Print $ n $ lines. Each of the $ n $ lines should contain $ m $ characters. Each of the characters should equal '0' or '1'. The $ j $ -th character of the $ i $ -th ( $ 0 $ -indexed) line should be equal to '1', in case the cell $ (i,j) $ is an appearance position, otherwise it should be equal to '0'.
