Step

same is true for the character 10-16. For substrings earlier than 9, the next [18] knows both the prefix of S and the suffix of S. The value 4 of next [9] indicates that the length of the prefix Suffix of the substring located before 9 is 4, The substring is included in the prefix of S, so the suffix of the substring is also included in the prefix of S, and the prefix of S is the suffix of S, therefore, the suffix of this substring is also the suffix of S. Forward until the length of the Child
