Problem Set 6(Autocube numbers)

Q. Autocube numbers are numbers having "n" digits such that the  last n digits of the cube  of the number will be the number itself. Write an algorithm and the subsequent Python code to check if the given number is autocube. Write a function to find the cube of a given number.. For example, 25 is a 2 digit autocube number with a cube  of 15625 and 376  with its  cube  53157376, is a 3 digit autocube number.

Input Format

First line contains the number to be checked

Output Format

Print Autocube or Not autocube 

Input:

The number

Processing Involved:

def autocube(n):

    temp = ''

    length = len(str(n))

    cube = n**3

    if int(str(cube)[-length:]) == n:

        print('Autocube')

    else:
        print('Not autocube')

        

Output:

Display whether the number is a autocube or not

Program:

def autocube(n):

    temp = ''

    length = len(str(n))

    cube = n**3

    if int(str(cube)[-length:]) == n:

        print('Autocube')

    else:

        print('Not autocube')

n = int(input())

autocube(n)

Algorithm:

Step1. Define the function autocube with one parameter n

Step1.1 assign temp as an empty string and length as length of the number n

Step1.2 assign cube as the cube of n

Step1.3 check if the last n digits of the cube are the number n if true the display not autocube else display autocube

Step2. get the number n

Step3. Call the function autocube to check if n is a autocube or not

Step4. End
