Write a method that prompts the user for 3 different integers and  
display on the screen on a single line, separated by commas. If one of the  
values is repeated, show only the repeated value.

- Use **[prompt()](https://developer.Mozilla.org/en-US/docs/Web/API/Window/prompt)** or [**createInput()**](https://p5js.org/reference/#/p5/createInput) w/ some message to prompt the user to enter the 3 numbers.
- Then apply [**trim()**](https://p5js.org/reference/#/p5/trim) followed by [**split()**](https://p5js.org/reference/#/p5/split) so it becomes an array.
- Force the array to have at max 3 number entries using [**min()**](https://p5js.org/reference/#/p5/min) like this:  
`array.length = min(3, array.length);`
- After that apply [**int()**](https://p5js.org/reference/#/p5/int) to remove any fractional parts from them.

I didn’t get this requirement part. Do you mean having unique values only?

If that’s so you can create a Set passing your array to it:

> The Set() constructor creates Set objects.

Then use the spread `...` syntax to convert it back to array: `array = [...new Set(array)];`
