Solution: Number of Longest Increasing Subsequence

Explore how to compute the number of longest strictly increasing subsequences in an integer array. Understand the use of dynamic programming by tracking subsequence lengths and counts at each array position, and learn to implement the algorithm with nested loops to optimize the solution.

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 ...
