When we need to calculate the answer to a range of length 1, its answer equals to one. That’s because any sequence of length one is a palindrome. Otherwise, if we reach an empty range, the answer to it is just zero. WebSep 24, 2024 · In mathematics, a subsequence is a sequence that can be derived from another sequence by deleting some elements without changing the order of the remaining elements.

WebApr 9, 2024 · To find the longest common subsequence, we traverse through both the strings - first and second using indexes i and j respectively. If first [i] = second [j], then we add this character to the result string and increment both i and j. If there is no match, that means that the subsequence was formed either by deleting first [i] or second [j]. WebOct 13, 2024 · Every recursive call finds the longest common subsequence of S [1 .. i] and T [1 .. j ]. The loop terminates when i = s and j = t, that is, when we’ve computed Opt ( S, T ).
