Hint

Each test point is scored independently.

This problem has $4$ scoring parameters $p_1, p_2, p_3, p_4$ ($p_1 \lt p_2 \lt p_3 \lt p_4$), which are given in the input file.

Your score will be determined by the following rules:

• If your answer differs from the standard answer by no more than $p_1$, you will receive full score for that test point.
• Otherwise, if your answer differs from the standard answer by no more than $p_2$, you will receive $70\%$ of the score for that test point.
• Otherwise, if your answer differs from the standard answer by no more than $p_3$, you will receive $40\%$ of the score for that test point.
• Otherwise, if your answer differs from the standard answer by no more than $p_4$, you will receive $10\%$ of the score for that test point.
• Otherwise, your score for that test point will be $0$.
