CCC '23 J1 - Deliv-e-droid

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

Sample Output 1

Explanation

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

Sample Output 2

Explanation

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 $0 - 100 + 0 = -100$.
