Given an array of integers, this problem seeks to find the length of the longest increasing subsequence within that array. A subsequence is defined as a sequence of elements that can be derived from another sequence by deleting some or no elements, without changing the order of the remaining elements. In the given example array, the longest increasing subsequence has a length of 6.
