# 1035.不相交的线

## 问题描述
[1035.不相交的线](https://leetcode.cn/problems/uncrossed-lines/)

## 解题思路
只是[1143.最长公共子序列](https://zwyyy456.vercel.app/zh/posts/tech/1143.longest-common-subsequence/)的另一种描述

## 代码
```cpp
#include <vector>
using std::vector;
class Solution {
  public:
    int maxUncrossedLines(vector<int> &nums1, vector<int> &nums2) {
        vector<vector<int>> dp(nums1.size() + 1, vector<int>(nums2.size() + 1, 0));
        for (int i = 1; i <= nums1.size(); i++) {
            for (int j = 1; j <= nums2.size(); j++) {
                if (nums1[i - 1] == nums2[j - 1])
                    dp[i][j] = max(max(dp[i - 1][j], dp[i][j - 1]), dp[i - 1][j - 1] + 1);
                else
                    dp[i][j] = max(dp[i - 1][j], dp[i][j - 1]);
            }
        }
        return dp[nums1.size()][nums2.size()];
    }
};
```
