Canadian Computing Competition: 2023 Stage 1, Junior #1

In the game, Deliv-e-droid, a robot droid has to deliver packages while avoiding obstacles. At the end of the game, the final score is calculated based on the following point system:

• Gain \(50\) points for every package delivered.
• Lose \(10\) points for every collision with an obstacle.
• Earn a bonus \(500\) points if the number of packages delivered is greater than the number of collisions with obstacles.

Your job is to determine the final score at the end of a game.

Input Specification

The input will consist of two lines. The first line will contain a non-negative integer \(P\) , representing the number of packages delivered. The second line will contain a non-negative integer \(C\) , representing the number of collisions with obstacles.

Output Specification

The output will consist of a single integer \(F\) , representing the final score.

Sample Input 1

5
2

Sample Output 1

730

Explanation for Sample 1

There are \(5\) packages delivered, so \(5 \times 50 = 250\) points are gained. There are \(2\) collisions, so \(2 \times 10 = 20\) points are lost. Since \(5 > 2\) , a bonus \(500\) points are earned. Therefore, the final score is \(250 - 20 + 500 = 730\) .

Sample Input 2

0
10

Sample Output 2

-100

Explanation for Sample 2

There are \(0\) packages delivered, so \(0 \times 50 = 0\) points are gained. There are \(10\) collisions, so \(10 \times 10 = 100\) points are lost. Since \(0 \le 10\) , no bonus points are earned. Therefore, the final score is \(0 - 100 + 0 = -100\) .
