Problem Name: Python - Map and Lambda Function

Problem Link: 

In this HackerRank Functions in PYTHON problem solution,

Let's learn some new Python concepts! You have to generate a list of the first N fibonacci numbers 0 being the first number. Then, apply the map function and a lambda expression to cube each fibonacci number and print the list.



The map() function applies a function to every member of an iterable and returns the result. It takes two parameters: first, the function that is to be applied and secondly, the iterables.
Let's say you are given a list of names, and you have to print a list that contains the length of each name.


>> print (list(map(len, ['Tina', 'Raj', 'Tom'])))  
[4, 3, 3]  


Lambda is a single expression anonymous function often used as an inline function. In simple words, it is a function that has only one line in its body. It proves very handy in functional and GUI programming.


>> sum = lambda a, b, c: a + b + c
>> sum(1, 2, 3)




Lambda functions cannot use the return statement and can only have a single expression. Unlike def, which creates a function and assigns it a name, lambda creates a function and returns the function itself. Lambda can be used inside lists and dictionaries.

Input Format

One line of input: an integer N.


0 <= N <

Output Format

A list on a single line containing the cubes of the first N fibonacci numbers.

Sample Input


Sample Output

[0, 1, 1, 8, 27]


The first 5 fibonacci numbers are [0,1,1,2,3], and their cubes are [0,1,1,8,27].






Code Examples

#1 Code Example with Python Programming

Code - Python Programming

cube = lambda x: x ** 3
sqrt = lambda x: x ** 0.5

def fibonacci(n):
    phi = (1 + sqrt(5)) / 2
    return [int((phi ** i - (1 - phi) ** i) / sqrt(5)) for i in range(n)]

if __name__ == '__main__':
    n = int(input())
    print(list(map(cube, fibonacci(n))))
