Given an an array of numbers, find the length of the longest possible subsequence that is increasing. This subsequence can "jump" over numbers in the array. For example in [3, 10, 4, 5] the longest increasing subsequence (LIS) is [3, 4, 5].
longestIncreasingSubsequence([3, 4, 2, 1, 10, 6]);
// should return 3, the length of the longest increasing subsequence:
// 3, 4, 6 (or 3, 4, 10)
