A small algorithmic problem, the topic title. What do you mean? is a very long pattern string such as "432a5234b5664c3243454", and then give a target string "ABC", as long as a string of strings in the pattern of colleagues containing each element of the target string can be. Requirements are very low. It is very easy to make a violent match, but the time complexity of the brute-force matching algorithm is very low (O (n^m)). The KMP algorithm is difficult to deal with this fuzzy match. How to i
