Towers of Hanoi Plus Music

It is programmed in Rust

For windows users, there is a version 0.1.0 Executable download. There are some batch files provided that show how to use a parameter to play music of different length.

For coders, there is a version 0.1.0 Full source download(Big, since it includes all dependencies).

There is also a version 0.1.0 small source download.

There is also a version 0.2.0 small source download where I fixed some technical issues (but didn't exactly make he music better).

There is also a version 0.3.0 small source and executable download where I'm using a single note per movement, which makes the music neater.

There is now a different version x small source and executable download where I'm creating the notes from the disc size, not from the movement.

There is now a version x 2 small source and executable download where the noise at the end of the waveform has been removed.
