Number of Burgers with No Waste of Ingredients in Python

Problem:

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 [].

Example 1:

Input: tomatoSlices = 16, cheeseSlices = 7

Output: [1,6]

Explantion:
To make one jumbo burger and 6 small burgers we need 4*1 + 2*6 = 16 tomato and 1 + 6 = 7 cheese. There will be no remaining ingredients.

Example 2:

Input: tomatoSlices = 17, cheeseSlices = 4

Output: []

Explantion:
There will be no way to use all ingredients to make small and jumbo burgers.

Example 3:

Input: tomatoSlices = 4, cheeseSlices = 17

Output: []

Explantion:
Making 1 jumbo burger there will be 16 cheese remaining and making 2 small burgers there will be 15 cheese remaining.

Example 4:

Input: tomatoSlices = 0, cheeseSlices = 0

Output: [0,0]

Example 5:

Input: tomatoSlices = 2, cheeseSlices = 1

Output: [0,1]

Constraints:

0 <= tomatoSlices <= 10^7

0 <= cheeseSlices <= 10^7

Solution:

class Solution:
    def numOfBurgers(tomatoSlices, cheeseSlices):
        jumboBurger = tomatoSlices - 2 * cheeseSlices
        if jumboBurger >= 0 and jumboBurger % 2 == 0:
            x = jumboBurger/2
            y = cheeseSlices - (jumboBurger / 2)
            if x >= 0 and y >= 0:
                return [x, y]
            else:
                return []
        return []


print(Solution.numOfBurgers(16, 7))
print(Solution.numOfBurgers(17, 4))
print(Solution.numOfBurgers(4, 17))
print(Solution.numOfBurgers(0, 0))
print(Solution.numOfBurgers(2, 1))
