hw-01 | programming language design - spring'2008, dr. s. yurttas - solution

rationale

This is your second assignment to practice and show that you're able to maintain/adapt a given application using existing/available tools, i.e., eclipse/visual studio.

You'll practice the fundamentals of programming using imperative and object-oriented language abstraction mechanisms in C++ and C# | Java to compose an application using multiple functions/methods/classes.

problem

You'll modify the given application which counts the frequency of set of patterns in a range(n1throughn2 inclusive) for each sequence as follows:

      -> dna filenames : dna-filenames.txt

      [ input sequences -
        dna-00 :
        ATCTCTAGTCATA
        TATCTATCTCTCT
        ACTCCTCTTCTCG
        TAGACTAGGACCT
        TCTTATCTATTCG
        GCCTTGTGGACCC

        dna-01 :
        .
        .
        .
      ]

      -> patterns filename : patterns.txt

      -> range begin : 2
                 end : 6

      [
        dna-00 : "aga" -
        ATCTCTAGTCATA - 2
        TATCTATCTCTCT - 1
        ACTCCTCTTCTCG - 1
        TAGACTAGGACCT - 0
        TCTTATCTATTCG - 0
        GCCTTGTGGACCC - 0

        dna-01 : "aga" -
        .
        .
        .

      ]

      [
        dna-00 : "cta" -

        .
        .
        .

        dna-01 : "cta" -

        .
        .
        .
      ]

Filename for the given datafiles and patterns are read in, interactively, using command-line/console.
For each file for each pattern for any range do the counting.
You'll do this repetitively until user decides as N, interactively.
You'll create one output file per pattern.
Modularization by functional decomposition and composition is the essence of the solution, as well as correctness.
You will use and reuse C#, Java, and C++ collections.
