# HackerRank Map and Lambda Function solution in python

In this Map and Lambda Function problem, 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.

## Problem solution in Python 2 programming.

```# Enter your code here. Read input from STDIN. Print output to STDOUT
def fib(n):
if n == 0:
return 0
if n == 1:
return 1
return fib(n-2) + fib(n-1)
n = int(raw_input())
cube = lambda x: x*x*x
print list(map(cube,[fib(a) for a in xrange(n)]))```

## Problem solution in Python 3 programming.

```cube = lambda x: pow(x,3)# complete the lambda function
def fibonacci(n):
# return a list of fibonacci numbers
lis = [0,1]
for i in range(2,n):
lis.append(lis[i-2] + lis[i-1])
return(lis[0:n])```

### Problem solution in pypy programming.

```cube = lambda x: x**3

def fibonacci(n):
# return a list of fibonacci numbers
result = [0,1]
for i in range(2,n):
result.append(result[i-1]+result[i-2])

return result[:n]```

### Problem solution in pypy3 programming.

```cube = lambda x: pow(x,3)# complete the lambda function

def fibonacci(n):
# return a list of fibonacci numbers
lis = [0,1]

for i in range(2,n):
lis.append(lis[i-2] + lis[i-1])

return(lis[0:n])
