Arrays HackerRank Solution In Python

Problem

The NumPy (Numeric Python) package helps us manipulate large arrays and matrices of numeric data.

To use the NumPy module, we need to import it using:

import numpy

Arrays

A NumPy array is a grid of values. They are similar to lists, except that every element of an array must be the same type.

import numpya = numpy.array([1,2,3,4,5])print a[1]          #2b = numpy.array([1,2,3,4,5],float)print b[1]          #2.0

In the above example, numpy.array() is used to convert a list into a NumPy array. The second argument (float) can be used to set the type of array elements.

Task

You are given a space separated list of numbers.

Your task is to print a reversed NumPy array with the element type float.

Input Format

A single line of input containing space separated numbers.

Output Format

Print the reverse NumPy array with type float.

Sample Input

1 2 3 4 -8 -10

Sample Output

[-10.  -8.   4.   3.   2.   1.]

Solution to HackerRank Arrays In Python

In this problem, we are to print out the given numbers as a floating point array.

import numpydef arrays(arr):    # complete this function    # use numpy.array    return numpy.array(arr[::-1], float)arr = input().strip().split(' ')result = arrays(arr)print(result)
