AlgorithmConcept: the DFS algorithm is a recursive process with a rollback process. For an undirected connected graph, after accessing a vertex V0 in the graph, access one of its adjacent vertex V1, then, starting from V1, access the illegally accessed neighboring vertices of V1, and continue until all the access vertices are accessed. Then, return to the last accessed vertex to see if there are any unaccessed vertex. If so, start from this vertex and

Title DescriptionAlice has n strings S_1,s_2...s_n,bob has a string set T, and the first collection is empty. The next thing that happens is the Q operation, which has two forms: "1 P", and Bob adds a string P to his own collection. "2 X", Alice asks Bob how many strings in a collection T contain string s_x. (We call string A contains string B, and if and only if B is a substring of a) Bob is in trouble and needs your help.InputLine 1th, a number n; next n lines, one string per line for s_i, nex
