Some of them are just straight forward extensions of a medium. For example think of a hypothetical string problem. An easy solution may require sorting and hashing substrings. A medium follow up for that may require using a Trie. And then a hard solution would be a double ended Trie or other methods. First see if you can solve the hard problem with brute force (TLE), and then think of ways to optimize that.
