Given an unsorted array of integers, find the length of longest increasing subsequence. For example, Given [10, 9, 2, 5, 3, 7, 101, 18], The longest increasing subsequence is [2, 3, 7, 101], therefore the length is 4. Note that there may be more than one LIS combination, it is only necessary for you to return the length.

	array = [10, 9, 2, 5, 3, 7, 101, 18, 31, 25, 68, 45, 12]


	# O(n^2)
	def longest_seqs(seqs):
	l = []
	for i in range(len(seqs)):
	l.append(max([l[j] for j in range(i) if l[j][-1] < seqs[i]] or [[]],
	key=len) + [seqs[i]])
	return len(max(l, key=len))
