You are given a 0-indexed array of strings words and a character x.
Return an array of indices representing the words that contain the character x.
Note that the returned array may be in any order.
Example 1:
Input: words = ["leet","code"], x = "e" Output: [0,1] Explanation: "e" occurs in both words: "leet", and "code". Hence, we return indices 0 and 1.
Example 2:
Input: words = ["abc","bcd","aaaa","cbc"], x = "a" Output: [0,2] Explanation: "a" occurs in "abc", and "aaaa". Hence, we return indices 0 and 2.
Example 3:
Input: words = ["abc","bcd","aaaa","cbc"], x = "z" Output: [] Explanation: "z" does not occur in any of the words. Hence, we return an empty array.
Constraints:
1 <= words.length <= 501 <= words[i].length <= 50x is a lowercase English letter.words[i] consists only of lowercase English letters.["leet","code"] "e" ["abc","bcd","aaaa","cbc"] "a" ["abc","bcd","aaaa","cbc"] "z"
