You have to show a simulation of rain in terminal.
In the example given below its adding 100 raindrops at random (use the default random function which your language offers) coordinates, waiting for 0.2 seconds and then redrawing again until the given time expires. Any character can be used for representing the raindrop.
- Wait time between redrawing in seconds.
- Time for which the rain will be visible. This is just an integer representing the number of iterations. [So, the net time for which the rain will be visible is this integer multiplied by the wait time]
- Message to be displayed when the rain ends. (This has to be centered)
- Number of raindrops to be displayed on the screen.
- A single byte should be used for representing a rain drop, and it can be anything, even cats and dogs.
- It doesn't have to be responsive to terminal size which means you don't have to handle the bug for varied terminal sizes. You can specify the terminal width and height on your own.
- Standard rules of golfing apply.
