Regular expressions are the standard way to represent the patterns in the strings. One symbol is '+' which represents all strings that have one or more occurrences of the preceding character. example: t+e+a+ represents any string s that has string of t's followed by string of e's followed by string of a's. Each of these strings of repeating letters must have atleast one character.
