Solution: Number of Longest Increasing Subsequence
Understand how to determine the number of longest strictly increasing subsequences in an integer array. Learn to apply dynamic programming by tracking subsequence lengths and counts at each array position. This lesson helps you develop an efficient O(n²) solution and grasp the method to update and accumulate counts for subsequences effectively.

Statement
Given an integer array nums, return the number of longest strictly increasing subsequences it contains.
A subsequence is formed by choosing elements from the array while keeping their original order, and it is considered strictly increasing if every next element is greater than the previous one.
