Okay kiddo, so lcs35 is something called an algorithm that helps us solve a really important problem. See, sometimes we have two big lists of things and we want to find the longest common subsequence between them. That means we want to find the longest list of things that are in both of our lists, but maybe not in the same order.
So how does lcs35 help us do that? Well, let's say we have two lists: A and B. We can use lcs35 to compare the first items in each list. If they're the same, great! We found a match. If not, we move on to the next item in list A and compare it to the first item in list B. We keep doing this until we find a match or we run out of items in one of the lists.
But wait, there's more! lcs35 doesn't just look at the first item in each list. It also keeps track of all the different possibilities it has explored so far. That way, if it comes across a dead end where there are no matches, it can go back and try a different path to see if that leads to a match.
Overall, lcs35 is like a really smart detective that helps us find the longest common subsequence between two big lists of things, even if they're not in the same order. Cool, huh?
