Concatenate

Problem Link : https://www.hackerrank.com/challenges/np-concatenate/problem

Difficulty : Easy

 

Tip

• Create input for creating numpy array like below
• a1 = [input().split() for _ in range(N)]
• so far a1 is string, need to convert it to int
• arr1 = numpy.array(a1, int)
• Concatenate arr1 and arr2 :)

 

Solution

import numpy as np N, M, P = list(map(int, input().split())) a1 = [input().split() for _ in range(N)] a2 = [input().split() for _ in range(M)] arr1 = np.array(a1, int) arr2 = np.array(a2, int) arr = np.concatenate((arr1, arr2), axis = 0) print(arr)
