 ## Description
+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: a = "11", b = "1"
-Output: "100"
+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.
 ```

-Find Words Containing Character
-```go
 ```
+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.
+```
