• 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.

Output for Sample Input 1Copy Anchor Link

730

Explanation of Output for Sample Input 1Copy Anchor Link

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 $250 - 20 + 500 =730$.

0
10

Output for Sample Input 2Copy Anchor Link

-100

Explanation of Output for Sample Input 2Copy Anchor Link

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 $0 \leq 10$, no bonus points are earned. Therefore, the final score is $0 - 100 + 0 = -100$.
