Longest Common Subsequence Programiz
The longest common subsequence LCS is defined as the longest subsequence that is common to all the given sequences provided that the elements of the subsequence are not required to occupy consecutive positions within the original sequences
Longest Increasing Subsequence LIS GeeksforGeeks, Create a recursive function For each recursive call Iterate from the i 1 to the current position and do the following Find the possible length of the longest increasing subsequence ending at the current position if the previous sequence ended at i Update the maximum possible length accordingly Repeat this for all indices and find the answer

Solved In General The Hardest Task Of Dynamic Programming Chegg
OK now to the more efficient O N log N solution Let S pos be defined as the smallest integer that ends an increasing sequence of length pos Now iterate through every integer X of the input set and do the following If X last element in S then append X to the end of S This essentially means we have found a new largest LIS Otherwise find the smallest element in S which is than X Algorithm How to determine the longest increasing subsequence using . A longest common subsequence LCS is the longest subsequence common to all sequences in a set of sequences often just two sequences It differs from the longest common substring unlike substrings subsequences are not required to occupy consecutive positions within the original sequences Define L i j to be the length of the longest common subsequence of X 0 i and Y 0 j Allow for 1 as an index so L 1 k 0 and L k 1 0 to indicate that the null part of X or Y has no match with the Analysis of LCS Algorithm We have two nested loops n The outer one iterates n times n The inner one iterates m times
