I’ve been trying to solve the “Longest Increasing Subsequence” problem using Python, and I’ve been following the tutorial on the Longest Increasing Subsequence Python. While the article provides a good explanation, I’m still having some trouble with the actual implementation.
Here’s the problem description briefly: Given an array of numbers, find the length of the longest increasing subsequence.
I’ve tried to implement the solution based on the article, but I’m running into some issues. Here’s my code so far:
# Python code for Longest Increasing Subsequence def longest_increasing_subsequence(nums): n = len(nums) lis =  * n for i in range(1, n): for j in range(0, i): if nums[i] > nums[j] and lis[i] < lis[j] + 1: lis[i] = lis[j] + 1 return max(lis) # Example usage nums = [10, 22, 9, 33, 21, 50, 41, 60, 80] result = longest_increasing_subsequence(nums) print("Length of Longest Increasing Subsequence:", result)
I’d appreciate it if someone could review my code and help me understand where I might be going wrong.
