Problem
sum
The sum tool returns the sum of array elements over a given axis.
By default, the axis value is None. Therefore, it performs a sum over all the dimensions of the input array.
prod The prod tool returns the product of array elements over a given axis. By default, the axis value is None. Therefore, it performs the product over all the dimensions of the input array.
Task
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 product of that result.
Input Format
The first line of input contains space separated values of N and M. The next N lines contains M space separated integers.
Output Format
Compute the sum along axis 0. Then, print the product of that sum.
