Medium • View on LeetCode • View on GitHub

Problem Description

Given two integers tomatoSlices and cheeseSlices. The ingredients of different burgers are as follows:

Jumbo Burger: 4 tomato slices and 1 cheese slice.
Small Burger: 2 Tomato slices and 1 cheese slice.

Return [total_jumbo, total_small] so that the number of remaining tomatoSlices equal to 0 and the number of remaining cheeseSlices equal to 0. If it is not possible to make the remaining tomatoSlices and cheeseSlices equal to 0 return [].

Solution

/**
 * @param {number} tomatoSlices
 * @param {number} cheeseSlices
 * @return {number[]}
 */
var numOfBurgers = function(tomatoSlices, cheeseSlices) {
  const jumbo = Math.floor((tomatoSlices - 2 * cheeseSlices) / (4 - 2));
  const small = cheeseSlices - jumbo;

  if (jumbo < 0 || small < 0 || jumbo * 4 + small * 2 !== tomatoSlices) {
    return [];
  }

  return [jumbo, small];
};
