How does C language output the only substring
How does C language output the only substring? in order to solve this problem, this article introduces the corresponding analysis and solution in detail, hoping to help more partners who want to solve this problem to find a simpler and easier way.
Topic description
Give a string and find all non-repeating substrings of length m. For example, if the string "aaab" is a substring of length 2, then it is "aa", "aa" and "ab" in turn, and the non-repetitive substrings are "aa" and "ab".
Input
The first line is an integer K, which represents the number of samples. The first line of each sample is an integer m, which represents the length of the requested substring. The second line is a string that consists entirely of lowercase letters and is no more than 100 in length.
Output
Output all unrepeated substrings in lexicographical order, with each sample finally outputting a blank line.
Sample input
two
two
Aaab
three
Aaab
Sample output
Aa
Ab
Aaa
This problem can define a two-dimensional array to hold all the substrings of the string, then sort it, and finally output one by one, only one of the same.
