1st 5 minutes = He thinks the code

2nd 5 minutes = He writes the code

3rd 5 minutes =  Break

4th 5 minutes = Write [ because he can type up to 10 minutes if he thinks for 5 minutes ]

5th 5 minutes = Think [ He has completed 10 minutes of writing so he has to think ]

6th 5 minutes =  Break

7th 5 minutes = He writes the code

8th 5 minutes = He writes the code

9th 5 minutes = Break

10th 5 minutes = He thinks the code

11th 5 minutes = He writes the code
