B'You are given a string s of length n, consisting of first k lowercase English letters. We define a c-repeat of some string q as a string, consisting of c copies of the string q. For example, string "acbacbacbacb" is a 4-repeat of the string "acb". Let 's say that string a contains string b as a subsequence, if string b can be obtained from a by erasing some symbols. Let p be a string that represents some permutation of the first k lowercase English letters. We define function d(p) as the smallest integer such that a d(p)-repeat of the string p contains string s as a subsequence. There are m operations of one of two types that can be applied to string s: All operations are performed sequentially, in the order they appear in the input. Your task is to determine the values of function d(p) for all operations of the second type. The first line contains three positive integers n, m and k (1 xe2 x80 x89 xe2 x89 xa4 xe2 x80 x89n xe2 x80 x89 xe2 x89 xa4 xe2 x80 x89200 xe2 x80 x89000, xe2 x80 x891 xe2 x80 x89 xe2 x89 xa4 xe2 x80 x89m xe2 x80 x89 xe2 x89 xa4 xe2 x80 x8920000, xe2 x80 x891 xe2 x80 x89 xe2 x89 xa4 xe2 x80 x89k xe2 x80 x89 xe2 x89 xa4 xe2 x80 x8910) -- the length of the string s, the number of operations and the size of the alphabet respectively. The second line contains the string s itself. Each of the following lines m contains a description of some operation: For each query of the second type the value of function d(p). After the first operation the string s will be abbbbba. In the second operation the answer is 6-repeat of abc: ABcaBcaBcaBcaBcAbc. After the third operation the string s will be abbcbba. In the fourth operation the answer is 5-repeat of cba: cbAcBacBaCBacBA. Uppercase letters means the occurrences of symbols from the string s.'...
