# HackerRank Sum and Prod problem solution in python

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))
