Recently n students from city S moved to city P to attend a programming camp.They moved there by train. In the evening, all students in the train decided that they want to drink some tea. Of course, no two people can use the same teapot simultaneously, so the students had to form a queue to get their tea.i-th student c...
For each test case print n integers. i-th of them must be equal to the second when i-th student gets his tea, or 0 if he leaves without tea.

David Blaine wants to sort the railway cars in the order of increasing numbers. In one move he can make one of the cars disappear from its place and teleport it...
Print a single integer — the minimum number of actions needed to sort the railway cars.

NoteIn the first sample the table is already good.In the second sample you may remove the first and third column.In the third sample you have to remove all the columns (note that the table where all rows are empty is considered good by definition).Let strings s and t have equal length. Then, s is lexicographically larg...

The first line contains two integers  — n and m (1 ≤ n, m ≤ 100). Next n lines contain m small English letters each — the characters of the table.

You are given an n × m rectangular table consisting of lower case English letters. In one operation you can completely remove one column from the table. The remaining parts are combined forming a new table. For example, after removing the second column from the tableabcdedfghijk we obtain the table:acdefghjk A table is...
Print a single number — the minimum number of columns that you need to remove in order to make the table good.
