P18272 [HackerRank] Map and lambda expression

题目描述

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

Concept

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)
6

Note:

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 $N$.

Constraints

$0\leq N\leq15$

Output Format

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

Sample Input
5

Sample Output
[0, 1, 1, 8, 27]

Explanation

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