PROBLEMAS_EM_C

A repository focused on study, practice, and growth in C programming, bringing together exercises, classical algorithms, advanced challenges, data structure implementations, sorting benchmarks, concurrency problems, and code experiments.

The purpose of this project is not only to store solutions, but also to serve as a study progress map, showing my evolution in C from basic programming logic to more demanding topics such as memory manipulation, data structures, time and space complexity, sorting algorithms, problem solving, and threads.

Repository Organization

Each main folder contains its own README.md with a more detailed explanation of:

• the contents covered;
• the purpose of the folder;
• the skills strengthened;
• the difficulty level of each problem or implementation;
• time and space complexity when relevant.

This root README works as a general overview and navigation point for the repository.

Goal

To build a solid foundation in C through continuous practice, documenting solutions and studies that help develop not only the ability to code, but also to analyze, optimize, compare, and justify algorithmic choices.
