In this **Sum and Prod** problem, You are given a 2-D array with dimensions N X M. Your task is to perform the sum tool over axis 0 and then find the products of that result.

## Problem solution in Python 2 programming.

import numpy m=map(int,raw_input().split()) n=[] for i in range(m[0]): n.append(map(int,raw_input().split())) print numpy.prod(numpy.sum(n,axis=0))

## Problem solution in Python 3 programming.

import numpy N, M = map(int, input().split()) A = numpy.array([input().split() for _ in range(N)],int) print(numpy.prod(numpy.sum(A, axis=0), axis=0))

### Problem solution in pypy programming.

# Enter your code here. Read input from STDIN. Print output to STDOUT import numpy N, M = map(int, raw_input().split()) myarr = [] for _ in range(N): myarr.append(map(int,raw_input().split())) print numpy.prod(numpy.sum(myarr, axis = 0), axis = 0)

### Problem solution in pypy3 programming.

# Enter your code here. Read input from STDIN. Print output to STDOUT import functools n, m = map(int, input().split()) a = [] for _ in range(n): a.append(list(map(int,input().split()))) #print(a) b = [sum(x) for x in zip(*a)] print(functools.reduce(lambda x,y: x*y, b))
