You are given two string arrays, queries and dictionary. All words in each array comprise of lowercase English letters and have the same length.
In one edit you can take a word from queries, and change any letter in it to any other letter. Find all words from queries that, after a maximum of two edits, equal some word from dictionary.
Return a list of all words from queries, that match with some word from dictionary after a maximum of two edits. Return the words in the same order they appear in queries.
Example 1:
Input: queries = ["word","note","ants","wood"], dictionary = ["wood","joke","moat"] Output: ["word","note","wood"] Explanation: - Changing the 'r' in "word" to 'o' allows it to equal the dictionary word "wood". - Changing the 'n' to 'j' and the 't' to 'k' in "note" changes it to "joke". - It would take more than 2 edits for "ants" to equal a dictionary word. - "wood" can remain unchanged (0 edits) and match the corresponding dictionary word. Thus, we return ["word","note","wood"].
Example 2:
Input: queries = ["yes"], dictionary = ["not"] Output: [] Explanation: Applying any two edits to "yes" cannot make it equal to "not". Thus, we return an empty array.
Constraints:
1 <= queries.length, dictionary.length <= 100n == queries[i].length == dictionary[j].length1 <= n <= 100- All
queries[i]anddictionary[j]are composed of lowercase English letters.
Hints
Hint 1
Try brute-forcing the problem.
Hint 2
For each word in queries, try comparing to each word in dictionary.
Hint 3
If there is a maximum of two edit differences, the word should be present in answer.
