Problem Number
1268
Problem Summary
The problem number 1268 is from the category of Trie in the LeetCode-75 curated list. This problem is of medium difficulty and involves designing a search suggestions system. The key pitfalls in this problem include efficiently implementing the trie data structure and handling cases where the search input does not match any words in the system.
Solution Summary
The best solution for problem 1268 in the LeetCode-75 curated list involves implementing a Trie data structure. The problem requires designing a search suggestions system, where given a set of products and a search word, the system should return a list of suggested products that match the search word prefix. To solve this, we can build a Trie with all the products and perform a prefix search for each search word. By traversing the Trie and collecting the suggestions, we can efficiently return the suggested products. The time complexity of this solution is O(N * M), where N is the number of products and M is the average length of the products' names.
