1276. Number of Burgers with No Waste of Ingredients

Medium

Math

Problem Explanation

Explanation:

To solve this problem, we can set up a system of linear equations based on the given constraints. Let x be the number of jumbo burgers and y be the number of small burgers. We can then form the following equations:

4x + 2y = tomatoSlices
x + y = cheeseSlices

We can solve these equations to find the values of x and y that satisfy both constraints. If x and y are integers and non-negative, we return [x, y]; otherwise, we return an empty list. :

Solution Code

class Solution {
    public List<Integer> numOfBurgers(int tomatoSlices, int cheeseSlices) {
        List<Integer> result = new ArrayList<>();
        
        if ((tomatoSlices - 2 * cheeseSlices) % 2 != 0) {
            return result;
        }
        
        int x = (tomatoSlices - 2 * cheeseSlices) / 2;
        int y = cheeseSlices - x;
        
        if (x >= 0 && y >= 0 && 4 * x + 2 * y == tomatoSlices) {
            result.add(x);
            result.add(y);
        }
        
        return result;
    }
}
