Hi everyone!

I'd like to know how to compute the length of an LCS (Longest Common Subsequence). I have the LCS-LENGTH(X,Y) code and it works fine, but I want to know how to fill a table by hand, i.e. inserting the length numbers and the arrows. I know some will tell me to follow the code but I can't understand how it works exactly. I need it to be explained to me in plain English. I can be a little dense at times!

Thanks for any help in advance!!
