Crafting regexes to avoid stack overflows

|
Due to the way regular expression matching is implemented in Java (and many other languages/libraries), matching a pattern may - depending on the regex - require stack space proportional to the length of the input. This means large inputs could cause the program to crash with a `StackOverflowException` when you ... Read More
