Sum and Product on a 2D Array – One-Liner Version #Python #HackerRank #OneLiner #NumPy #ArrayOperati

This solution provides a concise one-liner approach to solve the problem. In one compact code block, it:

Reads the dimensions of the array and the subsequent rows of space-separated integers.

Converts the input into a NumPy array.

Computes the sum of the array along axis 0 (i.e., the sum of each column).

Computes the product of these sums.

Prints the final result.

This one-liner approach leverages the power of NumPy's functions and Python's compact syntax, making it ideal for competitive programming and interview scenarios where brevity and efficiency are key.

Code (One-Liner Version):

import numpy as np
def solve():
if __name__ == '__main__':
solve()
