Program Information

Name: Grep
Domain: Algorithm
Functionality: Searches file for lines containing a match to a specified pattern.
Input:
     Fs = Ff, REf is construct by completely decomposing substring ‘[x1,…,xn]’ in REs into ‘x1|…|xn’, i.e. an equivalent format of regular expression.
Output:
     Lines in F that match RE (Type: ostream)
