Implementation of T9 contacts search algorithm for IZP course

gcc and make are the only requirements. Linux is preferred, but this should also build and run on macOS

1. Clone this repo
2. cd t9search
3. make

• ./t9search < telbook.txt - will output every contact in telbook.txt in formatted form

• ./t9search 264 < telbook.txt - will perform search over telbook.txt with the given query

  Output:

  Bohuslav Krena, 420541141233
  Bohuzel Nedambody, 420541141233
  

• ./t9search 111 < telbook.txt - will not find anything

  Output:

  Not found
  

Tested on both merlin and eva servers. Should also be compilable on macOS using it's built-in clang. Most work done in CLion connected to WSL Ubuntu 20.04
