# 100 Doors
> Imagine a hundred closed doors in a corridor.
> You go and open every one of them.
> Then, you open every second one. (If the door was open, then just close it.)
> Then, every third. Then, every fourth and every fifth and so on until you only touch the 100th door.
> How many doors are open now?
This is a mathematical problem known as "100 Doors". I have written a smol
program in Rust that calculates and visualizes the solution using
[ncurses-rs](https://crates.io/crates/ncurses).
```
A simple program that calculates and visualizes the "100 Doors" problem
Usage: hundred-doors [OPTIONS] [NUMBER]
Arguments:
[NUMBER] How many doors there are [default: 100]
Options:
-d, --draw Whether there should be a graphical representation of these doors
-e, --explain Whether to explain the problem
--twave How many milliseconds to wait before the next wave [default: 0]
--tdoor How many milliseconds to wait between new doors [default: 0]
-h, --help Print help
-V, --version Print version
```
## Examples
```
$ hundred-doors 100
> 10
```
```
$ hundred-doors 100 --draw --tdoor 10 --twave 50
```
You'll see an "animation" of the respective doors. Here's a screenshot:
