Prolog:

This kata series was created for friends of mine who just started to learn programming. Wish you all the best and keep your mind open and sharp!

Task:

A magician in the subway showed you a trick, he put an ice brick in a bottle to impress you.The bricks width and height are equal, forming a square. Just for fun and also to impress the magician and people around, you decided to calculate the brick’s volume. Write a function iceBrickVolume that will except these parameters:

radius – bottle’s radius (always > 0);

bottleLength – total bottle length (always > 0);

rimLength – length from bottle top to brick (always < bottleLength); And return volume of ice brick that magician managed to put into a bottle. Note: All inputs are integers. Examples: iceBrickVolume(1, 10, 2); // => 16

iceBrickVolume(5, 30, 7); // => 1150

*/

const iceBrickVolume = (r, x, y) => 2 * r * r * (x – y);
