Minimum Cowphabet Sing-throughs for an Observed String
A cow's language, known as Cowphabet, consists of the 26 lowercase letters. However, the order in which a cow recites these letters is a permutation of the standard alphabet sequence. Bessie repeats this song, and Farmer John notes down a string of letters he remembers hearing. The task is to determine the minimum number of complete Cowphabet r ...
