The substring matched by the group is accessible by name. (?P=name) Matches the text matched earlier by the group named name. (?#...) A comment; ignored. (?=...) Matches if ... matches next, but doesn't consume the string. (?!...) Matches if ... doesn't match next. (?
startIndex:It is the starting index of the substring. At this index, the character is included in the substring. If the startIndex value is not set then, it is assumed to equal to 0. endIndex:It is the last index of the substring. At this index, the character is not included in th...
and conclude that the last one is clearly the best. It turns out that “Yankees” and “New York Yankees” are a perfect partial match…the shorter string is a substring of the longer. We have a helper function for this too (and it’s far more efficient than the simplified algorithm I...
