You have to create a method "compoundArray" which should take as input two int arrays of different length and return one int array with numbers of both arrays shuffled one by one. 
```Example: 
Input - {1,2,3,4,5,6} and {9,8,7,6} 
Output - {1,9,2,8,3,7,4,6,5,6}
```

Difficulty: EASY
Starter code: def compound_array(a, b):
	

Solutions:
def compound_array(a, b):
	x = []
	while a or b:
		if a:
			x.append(a.pop(0))
		if b:
			x.append(b.pop(0))
	return x


def compound_array(a, b):
	x = min(map(len, (a, b)))
	return sum(map(list, zip(a, b)), []) + a[x:] + b[x:]


def compound_array(a, b):
	res = []
	for i in range(max(len(a), len(b))):
		res.extend(a[i:i + 1])
		res.extend(b[i:i + 1])
	return res


def compound_array(a, b):
	r = []
	while a or b:
		r += a[:1] + b[:1]
		(a, b) = (a[1:], b[1:])
	return r


def compound_array(a, b):
	return [l[i] for i in range(max(len(a), len(b))) for l in (a, b) if i < len(l)]


def compound_array(a, b):
	answer = []
	while a or b:
		if a:
			answer.append(a.pop(0))
		if b:
			answer.append(b.pop(0))
	return answer


def compound_array(a, b):
	lst = zip(a[:len(b)], b[:len(a)])
	return [item for sublist in lst for item in sublist] + a[len(b):] + b[len(a):]


from itertools import zip_longest

def compound_array(a, b):
	mx = []
	for (a, b) in zip_longest(a, b):
		mx.append(a)
		mx.append(b)
	return list(filter(lambda x: x != None, mx))


def compound_array(a, b):
	r = []
	for i in [[i, j] for (i, j) in zip(a, b)]:
		r.append(i[0])
		r.append(i[1])
	return r + a[min(len(a), len(b)):] + b[min(len(a), len(b)):]


def compound_array(a, b):
	if a == [] or b == []:
		return a + b
	n = []
	for x in range(len(min([a, b], key=len))):
		n.append(a[x])
		n.append(b[x])
		if x == len(min([a, b], key=len)) - 1:
			n += max([a, b], key=len)[x + 1:]
	return n
