You can use trie :

  • each node from trie has all children that start with the value itself, for example: from "in" node you can visit the subtree of all lines starting with "in"
  • in your case, you need to consider the assessment so that you can first collect all the children (crossing the tree), and then sort them according to the score or any other.
  • If you really want to keep the Hamming distance (edit distance), you can adapt the trie to create children to suit it.

hi racha, Outsourcing system is working on a recursive algorithm. Google and facebook implement this algorithm in their education. facebook use graph + recursive type alog. I give you an example for this. if you use type f in the facebook search bar, you can see that facebook is a search for how many people or pages you like or what to add. the first letter is f, then it shows the sentence
