Examples
products = ["mobile","mouse","moneypot","monitor","mousepad"], searchWord = "mouse"[["mobile","moneypot","monitor"],["mobile","moneypot","monitor"],["mouse","mousepad"],["mouse","mousepad"],["mouse","mousepad"]]products sorted lexicographically = ["mobile","moneypot","monitor","mouse","mousepad"]. After typing m and mo all products match and we show user ["mobile","moneypot","monitor"]. After typing mou, mous and mouse the system suggests ["mouse","mousepad"].
products = ["havana"], searchWord = "havana"[["havana"],["havana"],["havana"],["havana"],["havana"],["havana"]]The only word "havana" will be always suggested while typing the search word.
Constraints
1 <= products.length <= 10001 <= products[i].length <= 30001 <= sum(products[i].length) <= 2 * 104All the strings of products are unique.products[i] consists of lowercase English letters.1 <= searchWord.length <= 1000searchWord consists of lowercase English letters.How Interview Coder Helps with Leetcode Problems
