Description
At last the first term at the University came to its finish. Android Vasya has already passed all the exams and wants to know if he gets a scholarship. There is the following practice of giving scholarship to students at the University:
- if a student has got satisfactory marks, the scholarship is not given,
- if a student has passed through the examination period with only excellent marks, he gets a personal scholarship,
- if a student doesn’t get a personal scholarship and his average mark is not less than 4.5, he gets a high scholarship,
- if a student gets neither high nor personal scholarship and doesn’t have satisfactory marks, he gets a common scholarship.
A satisfactory mark corresponds to value 3, a good mark corresponds to value 4, and an excellent mark corresponds to value 5. An average mark for a student is the average value of all the marks this student got in his exams. Help Vasya find out which scholarship he gets.
Input
The first line contains an integer n that is the number of exams (1 ≤ n ≤ 10). In the i-th of the next n lines there is an integer mi that is value of Vasya’s mark in i-th exam (3 ≤ mi ≤ 5).
Output
If Vasya doesn’t get any scholarship output “None”. If he gets a common scholarship output “Common”, if he gets a high scholarship output “High”, if he gets a personal one output “Named”.
