Acommon subsequenceof two strings is a subsequence that is common to both strings. Example 1: Input:text1 = "abcde", text2 = "ace"Output:3Explanation:The longest common subsequence is "ace" and its length is 3. Example 2: Input:text1 = "abc", text2 = "abc"Output:3Explanation:The ...
LCSis"AC" 这个题目思路是利用dynamic programming,用二维的,mem[l1 + 1][l2 + 1] # mem[i][j] 去表示s1的前i个characters与s2的前j个characters的LCS的length。 function : mem[i][j] = max(mem[i][j - 1], mem[i - 1][j]) if s1[i - 1] != s2[j - 1] max(mem[i][j - 1]...

both of them. A subsequence is a sequence that appears in the same relative order, but not necessarily contiguous. For example, “abc”, “abg”, “bdf”, “aeg”, ‘”acefg”, .. etc are subsequences of “abcdefg”. So a string of length n has 2^n different possible subsequences....
