Seeking Help with Longest Increasing Subsequence in C++

[Avantika_Sharmaa24]

Hello everyone,

I've been trying to implement the Longest Increasing Subsequence in C++ algorithm after reading about Longest Increasing Subsequence C++.

I'm having some trouble with my code, and I was wondering if someone could help me out. Here's the C++ code I've written so far:

PHP Code:

#include <iostream>
#include <vector>

using namespace std;

int longestIncreasingSubsequence(vector<int>& nums) {
    int n = nums.size();
    vector<int> dp(n, 1);

    for (int i = 1; i < n; i++) {
        for (int j = 0; j < i; j++) {
            if (nums[i] > nums[j]) {
                dp[i] = max(dp[i], dp[j] + 1);
            }
        }
    }

    int maxLen = 0;
    for (int i = 0; i < n; i++) {
        maxLen = max(maxLen, dp[i]);
    }

    return maxLen;
}

int main() {
    vector<int> nums = {10, 22, 9, 33, 21, 50, 41, 60, 80};
    int result = longestIncreasingSubsequence(nums);
    cout << "The length of the longest increasing subsequence is: " << result << endl;
    return 0;
} 


My code is close to the correct solution, but I'm not getting the expected output. Can someone please review my code and point out where I might be going wrong? Any help or suggestions would be greatly appreciated.
