In this **Zipped!** problem The National University conducts an examination of N students in X subjects. Your task is to compute the average scores of each student.

# Problem solution in Python 2 programming.

N,X = map(int,raw_input().split()) marks = [] for i in xrange(X): marks.append(map(float,raw_input().split())) for studentScores in zip(*marks): print sum(studentScores)/len(studentScores)

## Problem solution in Python 3 programming.

# Enter your code here. Read input from STDIN. Print output to STDOUT n, x = map(int, input().split()) sheet = [] for _ in range(x): sheet.append( map(float, input().split()) ) for i in zip(*sheet): print( sum(i)/len(i) )

### Problem solution in pypy programming.

# Enter your code here. Read input from STDIN. Print output to STDOUT n, x = map(int, raw_input().split()) all_scores = [map(float, raw_input().split()) for _ in xrange(x)] for student, score in zip(range(1, n+1), zip(*all_scores)): print sum(score)/x
