What is grep?

Grep is a command-line utility for searching plain-text data sets for lines that match a regular
expression or simply a string. E.g.

Part b:

My Grep Algorithm = 248ms

My Naïve Algorithm = 366ms

Reasoning:

• My grep algorithm performed 32.2% better than the naïve algorithm.
• My grep algorithm is more efficient and faster than naïve.
• Naïve only takes one position movement at each time making it inefficient.
• In my grep algorithm, it does not match characters that we already know will match.
• When naïve finds a position, it does not use it to find another, instead it goes back to the starting point and looks for pattern all over again.
• The grep algorithm reuses the information from the previous shift rather than disregarding it.
