Transpose and Flatten in Python | HackerRank Solution

Hello coders, today we are going to solve Transpose and Flatten HackerRank Solution in Python.

Transpose and Flatten in Python



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 numpy

my_array = numpy.array([[1,2,3],
print numpy.transpose(my_array)

[[1 4]
 [2 5]
 [3 6]]


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

import numpy

my_array = numpy.array([[1,2,3],
print my_array.flatten()

[1 2 3 4 5 6]


You are given a NM 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 2
1 2
3 4

Sample Output

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

Solution – Transpose and Flatten in Python

import numpy
n,m = map(int,input().split())
ar = []
for i in range(n):
    row = list(map(int,input().split()))
np_ar = numpy.array(ar)
