- Created empty solution files for various exercises in strings, modules, hashmaps, options, error handling, generics, traits, lifetimes, tests, iterators, smart pointers, threads, macros, clippy, conversions, and quizzes. - Each solution file contains a main function with a comment indicating that it will be automatically filled after completing the exercise. - Added a README.md file to provide information about the solutions and their purpose.
