Solution: Number of Longest Increasing Subsequence

Explore how to determine the count of the longest strictly increasing subsequences in an integer array using dynamic programming. Learn to track subsequence lengths and counts efficiently to solve complex optimization problems.

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.
