The KMP algorithm helps us to avoid unnecessary backtracking while searching for the pattern. In the naïve approach, we search in each substring of length M, but here we don't need to backtrack in the gi
Searching the database like this is efficient & brings back only customers which are at least vaguely plausible as matches. This approach is not perfect — excessive misspelling can cause the database search to miss — but users can easily retype & search again. If failed matches are a freque...

Concatenation (combining two or more strings), substring extraction (obtaining a segment of a string) and searching for certain characters or patterns inside a string are some frequent operations that can be carried out on strings. Methods We can use following methods to determine whether string's...
There may be cases when we want to locate a substring but only after a certain number of characters. In such cases, we can pass the second argumentfromIndexthat skips the specified number of characters and then starts searching from the substring or the character. ...
