Given this leetcode problem, can you please give me 3 one word hints?

```
Given an input string (s) and a pattern (p), implement wildcard pattern matching with support for '?' and '*' where:

'?' Matches any single character.
'*' Matches any sequence of characters (including the empty sequence).
The matching should cover the entire input string (not partial).
``` In your response, capitalize a few words to stress main points. Please limit the number of words with all capital letters to less than 8.
