In this kata, your task is to write a function `to_bytes(n)` (or `toBytes(n)` depending on language) that produces a list of bytes that represent a given non-negative integer `n`. Each byte in the list is represented by a string of `'0'` and `'1'` of length 8. The most significant byte is first in the list. The example test cases should provide you with all the details. You may assume that the argument `n` is valid.

Difficulty: EASY
Starter code: def to_bytes(n):
	

Solutions:
def to_bytes(n):
	if not n:
		return ['00000000']
	res = []
	while n:
		res.append('{:08b}'.format(n % 256))
		n //= 256
	return res[::-1]

to_bytes = b = lambda n, f=1: n and b(n >> 8, 0) + [format(n & 255, '08b')] or ['0' * 8] * f


def to_bytes(n):
