This repository serves as a log for my journey in learning and practicing data structures and algorithms. It is structured around exercises and examples from notable texts in the field, including "Introduction to Algorithms, Fourth Edition" and "Competitive Programming Volumes 1 and 2" by Helix Hamin.

The repository is organized into two main directories:

• CP-Volumen1: Contains chapters and exercises related to Competitive Programming Volume 1.
• Estructuras_Algoritmos: Includes exercises and examples focusing on various data structures and algorithms.

Each chapter directory contains problem sets, source code, input/output files, and a dedicated Makefile for compiling and testing the code.

The repository is configured with a Makefile that includes default values for the problem type (t) and problem number (n), which are set to 'u' (UVA) and '1', respectively. These values can be overridden by specifying them when running the make command.

The Makefile is set up to dynamically select source directories and files based on the type of problem (UVA or Kattis). The following is a simplified explanation of the Makefile's compilation process:

• Directory Configuration: Automatically determines the working directory paths for UVA and Kattis problem files.
• Compiler Settings: Uses g++ for compiling C++ files.
• Source and Executable Configuration: Depending on the problem type (t), it selects the appropriate source directory and source file. It compiles the source file into an executable named a.out in the same directory.

To compile a solution, use the command:

make compile t=[u/k] n=[problem_number]

Where:

• t specifies the type of problem (u for UVA, k for Kattis), default is 'u'.
• n is the problem number, default is '1'.

This setup allows for flexible compilation based on the problem source and type, streamlining the process for different problem sets.

The Makefile includes several rules for running and testing the compiled solutions, accommodating both detailed checks against expected outputs and quicker execution checks without comparison.

These commands execute the compiled solution, redirecting input.txt as input and comparing the actual output against output_expected.txt to verify correctness:

• For UVA problems:

  make run_uva

• For Kattis problems:

  make run_kattis

The outputs are written to output.txt and then compared to output_expected.txt using the diff command. Any differences are displayed, indicating discrepancies from expected results.

For rapid testing without output verification:

• General execution command (chooses based on t variable):

  make run

• Execute UVA solution:

  make runu

• Execute Kattis solution:

  make runk

These commands directly run the compiled executable a.out, which can be useful for quick checks or debugging.

To remove all compiled and temporary files from both the UVA and Kattis directories, use:

make clean

This command cleans the directories by removing all .o and .out files, helping maintain a tidy workspace.
