Solution

Approach 1: Dynamic Programming

The code is shown below:

class Solution:
    def maxUncrossedLines(self, nums1: List[int], nums2: List[int]) -> int:
        dp = [[0] * (len(nums2) + 1) for _ in range(len(nums1) + 1)]
        for i in range(1, len(nums1) + 1):
            for j in range(1, len(nums2) + 1):
                if nums1[i-1] == nums2[j-1]:
                    dp[i][j] = dp[i-1][j-1] + 1
                else:
                    dp[i][j] = max(dp[i-1][j], dp[i][j-1])
        return dp[-1][-1]
