Chef and Cook-Off Codechef Solution

Chef and Cook-Off Codechef Solution: Chef has obtained the results of a past Cook-Off. He wants to estimate the skill level of each contestant. The contestants can be classified with high probability (w.h.p.) based on the number of solved problems:

  • A contestant that solved exactly 0 problems is a beginner.
  • A contestant that solved exactly 1 problem is a junior developer.
  • A contestant that solved exactly 2 problems is a middle developer.
  • A contestant that solved exactly 3 problems is a senior developer.
  • A contestant that solved exactly 4 problems is a hacker.
  • A contestant that solved all five problems is Jeff Dean.

Please help Chef to identify the programming level of each participant.

Input

  • The first line of the input contains a single integer N denoting the number of competitors.
  • N lines follow. The i-th of these lines contains five space-separated integers Ai, 1, Ai, 2, Ai, 3, Ai, 4, Ai, 5. The j-th of these integers (1 ≤ j ≤ 5) is 1 if the i-th contestant solved the j-th problem and 0 otherwise.

Output

For each participant, print a single line containing one string denoting Chef’s classification of that contestant — one of the strings “Beginner”, “Junior Developer”, “Middle Developer”, “Senior Developer”, “Hacker”, “Jeff Dean” (without quotes).

Constraints

  • 1 ≤ N ≤ 5000
  • 0 ≤ Ai, j ≤ 1 for each valid ij

Sample Input 1 

7
0 0 0 0 0
0 1 0 1 0
0 0 1 0 0
1 1 1 1 1
0 1 1 1 0
0 1 1 1 1
1 1 1 1 0

Sample Output 1 

Beginner
Middle Developer
Junior Developer
Jeff Dean
Senior Developer
Hacker
Hacker

Explanation

The first contestant has no solved problems, therefore he is a beginner. The second contestant solved 2 problems (the second and fourth problem), therefore he has the skills of a middle developer. The third contestant solved 1 problem, therefore he’s at the expected level of a junior developer. The fourth contestant solved 5 problems — we can guess it was Jeff Dean. The fifth contestant solved 3 problems, so he is a senior developer. And the last two contestants should be hackers because they solved exactly 4 problems each.

Chef and Cook-Off – CodeChef Solution in Python

t = int(input())
d = {0:'Beginner',1:"Junior Developer",2:"Middle Developer",3:"Senior Developer",4:"Hacker",5: "Jeff Dean"}
for i in range(t):
    l = list(map(int,input().split()))
    print(d[l.count(1)])
