HDU_1960 If you think of each route as a point, and then after task I is completed, you can rush to the task j and even a directed edge of I-> j, in this way, we get a directed acyclic graph, and the question is equivalent to covering all the

If P [1... k] and P [L-k + 1... l] match (L is the string length), then P [L-k + 1... l] This character must be repeated in P [1... l]-P [L-K + 1... l. Proof Method: if this section is not repeated, P [1... K] and P [L-k + 1... L] cannot match. You

I'm using a map that first sorts the words by the number of letters they appear, and then sort the output. Note that if a word appears more than two times, then the output group size is also counted, but the output word is the time to output the
