Looks like for printing LCS, we can always use only the last row in the table. i = m-1; for (int j=0; j < n; j++) if (t[i][j] != t[i][j+1]) cout

[@rahilsanghavi9347]

That's a very good observation bro

[@kartikeshwarhingole6007]

Yeah, Bro your solution is absolutely correct. I used your method to find the longest sub-sequence string in leetcode problem "Longest Common Subsequence" , and then returned the length of the string to verify, and solution was accepted. Basically I just used the code of "Longest Common Sub-Sequence" and just utilised the last row for my answer. int dp[1002][1002]; class Solution { public: int longestCommonSubsequence(string s1, string s2) { int i, j, n=s1.length(), m=s2.length(); string s; for(i=0;i

Nice Video Bhai. Just a minor suggestion which wont make much of a difference but the reverse part for getting the LCS isn't required. If we know the length of the sequence, we can just create a char array of length = lcs and start from the rightmost end/index of the char array and copy the characters which match accordingly. You are doing a wonderful job Bhai :) Cheers.

[@kumarivandana1554]

You can still make it better by writing in this way ans = a[i-1] + ans; where ans is the string to be returned.

[@dragonoid296]

@@kumarivandana1554 not as optimized because appending in the front takes O(n)

[@vaibhavkumar267]

I had a doubt, during the creation of table " t ", we do check for characters to be similar ( with this code : if a[i-1] == b[j-1] and then we do necessary increments for the LCS count ), then we can actually push the characters to a string at that very moment right ? Like instead of performing what Aditya just said in the above video. EDIT : My method was wrong, I dry run the code and checked, we will get multiple chars as well so the above approach is the right one .

This problem can be solved in another method just like original LCS problem. Initialize first row and column with empty strings. As we iterate if match happens we keep adding the character and store the string itself in t matrix. last element will be the answer. For length we can just measure length of the final string. We can even print all possible subsequences easily by this approach. And we don't have to do anything after filling the t matrix.

[@Vendettaaaa666]

You can also think of this approach like a Depth First Search and we choose "adjacents" based on the choices we previously made in the past to build the 2D array.
