Otherwise, we add the index of the occurrence to the list and increment the start variable by 1. Notice that the function in the example finds indexes of overlapping substrings as well. main.py def find_indexes(a_string, substring): start = 0 indexes = [] while start < len(a_string)...
hello,i have tried to compute longest common substring for more than 2 string. i read dp solution in wikipedia.We can compute it with O(min(a,b)) memory and O(ab) time. but i don't know how to do this with 3 or more strings,when string sizes are two big-1000000; please help ...
You have a large String S, and q queries, each query consist of a small string b. The answer of each query is to find thelengthof the longest common substring between S and b. ( |S| <= 10^5, |b| <= 100, q <= 100 ) My dp solution to find the length of the largest LCS ...

-- The following SQL query uses the FIND_IN_SET() function to find the position of the string 'ank' within a comma-separated list of strings.SELECTFIND_IN_SET('ank','b,ank,of,monk'); Explanation: This SQL query calls the FIND_IN_SET() function to search for the substring 'ank' ...
The substring with start index= 2 is "ab", which is an anagram of "ab". 这道题先想到了用hash存一下p出现的字符和个数,然后遍历s来做。但超时了: classSolution {publicList<Integer>findAnagrams(String s, String p) { List<Integer> resList =newArrayList<>();if(s ==null|| p ==null){...
In mathematical terms, the algorithm has a Big-O notation of O(m*(n-m)), where m is the length of the word and n is the length of the text string. This approach may be appropriate for haystack text strings of a few thousand characters but will be intolerably slow if there are ...
