 ## Description
+You have a chat log of `n` messages. You are given two string arrays `messages` and `senders` where `messages[i]` is a **message** sent by `senders[i]`.
+
+A *message** is list of **words** that are separated by a single space with no leading or trailing spaces. The **word count** of a sender is the total number of **words** sent by the sender. Note that a sender may send more than one message.
+
+Return the sender with the **largest** word count. If there is more than one sender with the largest word count, return the one with the **lexicographically largest** name.
+
+**Note**:
+
+- Uppercase letters come before lowercase letters in lexicographical order.
+- `"Alice"` and `"alice"` are distinct.
 
 **Example 1:**
 
 ```
-Input: a = "11", b = "1"
-Output: "100"
+Input: messages = ["Hello userTwooo","Hi userThree","Wonderful day Alice","Nice day userThree"], senders = ["Alice","userTwo","userThree","Alice"]
+Output: "Alice"
+Explanation: Alice sends a total of 2 + 3 = 5 words.
+userTwo sends a total of 2 words.
+userThree sends a total of 3 words.
+Since Alice has the largest word count, we return "Alice".
 ```

-Sender With Largest Word Count
-```go
 ```
-
+Input: messages = ["How is leetcode for everyone","Leetcode is useful for practice"], senders = ["Bob","Charlie"]
+Output: "Charlie"
+Explanation: Bob sends a total of 5 words.
+Charlie sends a total of 5 words.
+Since there is a tie for the largest word count, we return the sender with the lexicographically larger name, Charlie.
