## Problem: Firm

A firm receives a request for creating a project for which a certain amount of hours are needed. The firm has a certain number of days. During 10% of the days, the workers are being trained and cannot work on the project. A normal working day is 8 hours long. The project is important for the firm and every worker must work on it in overtime for 2 hours per day.

The hours must be rounded down to the nearest integer (example -> 6.98 hours are rounded to 6 hours).

Write a program that calculates whether the firm can finish the project on time and how many hours more are needed or left.

### Input Data

The input data is read from the console and contains exactly three lines:

• On the first line are the needed hoursan integer in the range of [0 … 200 000].
• On the second line are the days that the firm hasan integer in the range of [0 … 20 000].
• On the third line are the number of all workersan integer in the range of [0 … 200].

### Output Data

Print one line on the console:

• If the time is enough:
• "Yes!{the hours left} hours left.".
• If the time is NOT enough:
• "Not enough time!{hours more needed} hours needed.".
