Problem Description
Have you got a driving license? Acquiring a driving license brings you a lot of benefits. You will regret for not passing the driving test or getting a driving license in your campus life. Why?College life is filled with much spare time,which you can use to improve yourself in many fields such as driving.
During the time of taking driving lessons,Samuel met a lot of classmates whose time are occupied by their own work. The fact that they have little time to practice makes getting driving license increasingly difficult. Passing the driving test as soon as possible is suggested by these mates to the our college students who cannot drive.
Know something about the driving test you can read the information in the background section,however,it is not related with this problem firmly. Surely,you can go to the problem section directly.
Here is the background information on owning driving licenses in China mainland:
To get a driving license successfully,you need to take about 4 tests at least.
The first part is the theory exam which helps you know clearly about the transportation law in China mainland and other driving theory.
The second is to test you whether you can drive a car forward out and backward in the garage at a very low speed(like aunts moving),move the car from one garage to another and drive out.
The third section you need to pass is a little difficult than the second test. In this section,you should be able to drive to avoid the obstacles on the road,manage your car pass S formed way(your car's wheels can not be moved onto one of the tracks which leads your way out),after that you may have to make your car pass the 90 degree angle track,then pass the course equipped with very low bridge using one side of your car's wheel and so on.
The forth part which is test the same day with the third test is called road driving test(but in the problem I designed the time between Part 3 and Part 4 is 1 month,just want to make the problem much easier).As you can refer from the word,it tests the ability of driving on the road,it is more practical and of more importance.
If you seems not very lucky,you will have fifth section(The problem does not include the 5th part,you can ignore it in solving the problem).In this part you are required to driving at night which involves changing lights in addition . Teachers never taught how to drive at night unless your group is asked to take part in this test. But on the contrary,taught how to driving at night,of course,is necessary. Samuel had an experience of taking the fifth test to get the driving license in the summer of 2008. Tell you a secret,next time you meet a car comes from an opposite direction and the driver of that car does not change his front lights ,it probably means he/she needs special training on how to drive at night.
To get a driving license,you should pass the 4 parts one by one. For example,if you failed in the section 2,you have to retry for a second time,third time...before you pass. After that you have the opportunity to enter Part 3.
Here is the problem section you need read patiently:
Some details you need to know:
1.The time between the two tests is generally about 1 month(If you fail in the test on your first attempt,you can try it a second time. Fail again the second time he have to go home and retry after 1 month).
2.And the time from you take the first test to your owning a license is within 2 years.
3.What's more,the passing score in Part 1 test is 90(that is to say if you get 89 or even lower at your first attempt,a second attempt is needed. You will pass until you get 90 or higher at the second time)and each of the rest parts the passing score is 80 at least.

Input
The input consists 2 major sections as usual,
the test cases t,each of the test case involves an integer n and n scores one gets in the test and with n scores he passed the test or he failed to pass in the 2 years(of course here n>=4). All the number here are integers.

Output
Output is simple. Just output the time one needs to get a driving license (if time is within 2 years)using the format “It takes about m months to get a driving license.”If time is beyond 2 years please output the sentence “He failed to get a driving license within 2 years! ”

Sample Input
3
5
89 90 95 84 80
7
80 90 70 80 75 85 80
7
80 90 70 70 80 85 85
