Transpose and Flatten HackerRank Solution In Python

Problem

Transpose

We can generate the transposition of an array using the tool numpy.transpose.
It will not affect the original array, but it will create a new array.

import numpymy_array = numpy.array([[1,2,3],                        [4,5,6]])print numpy.transpose(my_array)#Output[[1 4] [2 5] [3 6]]

Flatten

The tool flatten creates a copy of the input array flattened to one dimension.

import numpymy_array = numpy.array([[1,2,3],                        [4,5,6]])print my_array.flatten()#Output[1 2 3 4 5 6]

Task

You are given a NXM integer array matrix with space separated elements (N = rows and M = columns).
Your task is to print the transpose and flatten results.

Input Format

The first line contains the space separated values of N and M.
The next N lines contains the space separated elements of M columns.

Output Format

First, print the transpose array and then print the flatten.

Sample Input

2 21 23 4

Sample Output

[[1 3] [2 4]][1 2 3 4]
