1276. Number of Burgers with No Waste of Ingredients

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

 

Should be an easy question..

class Solution {
    public List<Integer> numOfBurgers(int tomatoSlices, int cheeseSlices) {
        
        List<Integer> result = new ArrayList<>();
        
        if (tomatoSlices % 2 ==1 || cheeseSlices * 4 < tomatoSlices || cheeseSlices * 2 > tomatoSlices){
            return result;
        }
        
        int x = (tomatoSlices - cheeseSlices*2)/2;
        result.add(x);
        result.add(cheeseSlices-x);
        
        return result;
    }
}
