Solution: Number of Longest Increasing Subsequence

Explore how to calculate the number of longest strictly increasing subsequences in an integer array using dynamic programming. Understand the approach that tracks subsequence lengths and counts at each position to solve complex optimization problems efficiently.

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.

Constraints:

  • 11 \le ...
