Best explanation, you have even told how these paths are building and we are finding the common alphabets. THANKS

SportTechNomad

Thank you so much! I finally understand how we get that table(or two matrix) step by step! This is the best explanation I found!

Thank You Very Much.
You explained the whole thing brilliantly.

LaRosmarinus

thank you, I finally get it. The chapter from the book explaining this was a nightmare

Thank you very much.You explained superbly where the plus one was coming from. chawa

very clear and easy to understand...thank you

deveshkumar

please add some parts on why the particular algorithm is used ( the logic behind it ) . Describing the logic from CLRS would be helpful.

sunandan

perfectly what i have been looking for. one suggestion if i can give you...:- explain a bit more in a lay man language.
thanx

Also there is a confusion the lectures i have had <--- arrow instead of up arrow when x and y doesn't match but they have same value, this brings change in the result

SportTechNomad

How would you go about discovering an algorithm such as this?

AaronOrtiz

isn't there a way to gather the indexes of the subsequence while iterating through the array ?

Dobra pomoc tylko dla początkujących programistów.

does it have to have sequence?
see both row and column has DCBA in order
but when i do other exercises, sometimes it does not have the sequence.
am i doing it correctly?

thank you

when do we use matrix vs an array in dynamic programming problems?

irvinge

I don´t understand the logic. What is the logic behind the process?

eduardoPicazzo

Why do we initialise first row and column with all elements as zero?

vivekpal

How is this logic explained here is dynamic programming strategy?

LDARSHAN

this is probably a dumb question but why is it using a matrix?
