Test instructions: Give n strings, order them in dictionary order, and then output them according to the rules.

= = = Study purple book, the topic meaning is very clear, the number of columns and the number of rows at the beginning of the first look at the wood to understand Ah ah Ah

Number of columns: that is (60-m)/(m+2) +1; that is, to subtract the last column first, count the average number of columns, and then add the last column

Number of lines: can be used in purple Book (n-1)/cols+1, also available ceil function

The coordinates are then counted as the first string, which is the top-to-bottom of the arrows in the graph.
