B"Mike and some bears are playing a game just for fun. Mike is the judge. All bears except Mike are standing in an n xe2 x80 x89 xc3 x97 xe2 x80 x89m grid, there's exactly one bear in each cell. We denote the bear standing in column number j of row number i by (i, xe2 x80 x89j). Mike's hands are on his ears (since he's the judge) and each bear standing in the grid has hands either on his mouth or his eyes. They play for q rounds. In each round, Mike chooses a bear (i, xe2 x80 x89j) and tells him to change his state i. e. if his hands are on his mouth, then he'll put his hands on his eyes or he'll put his hands on his mouth otherwise. After that, Mike wants to know the score of the bears. Score of the bears is the maximum over all rows of number of consecutive bears with hands on their eyes in that row. Since bears are lazy, Mike asked you for help. For each round, tell him the score of these bears after changing the state of a bear selected in that round. The first line of input contains three integers n, m and q (1 xe2 x80 x89 xe2 x89 xa4 xe2 x80 x89n, xe2 x80 x89m xe2 x80 x89 xe2 x89 xa4 xe2 x80 x89500 and 1 xe2 x80 x89 xe2 x89 xa4 xe2 x80 x89q xe2 x80 x89 xe2 x89 xa4 xe2 x80 x895000). The next n lines contain the grid description. There are m integers separated by spaces in each line. Each of these numbers is either 0 (for mouth) or 1 (for eyes). The next q lines contain the information about the rounds. Each of them contains two integers i and j (1 xe2 x80 x89 xe2 x89 xa4 xe2 x80 x89i xe2 x80 x89 xe2 x89 xa4 xe2 x80 x89n and 1 xe2 x80 x89 xe2 x89 xa4 xe2 x80 x89j xe2 x80 x89 xe2 x89 xa4 xe2 x80 x89m), the row number and the column number of the bear changing his state. After each round, print the current score of the bears."...
