Implementation Information

The code is spread trough five Rust source files to make reading them individually easier. The functions are divided as follows:

• src/main.rs: the main function of the program
• src/file.rs: opening a file and reading the initial words
• src/info.rs: functions that compute the bits of a word, update them and pick the words with the most bits
• src/matcher.rs: functions that update the possible words based on the last tried word
• src/read.rs: functions that read the data from the user
