 ## Description
+A word is considered **valid** if:
+
+- It contains a **minimum** of 3 characters.
+- It contains only digits (0-9), and English letters (uppercase and lowercase).
+- It includes **at least** one **vowel**.
+- It includes **at least** one **consonant**.
+
+You are given a string `word`.
+
+Return `true` if `word` is valid, otherwise, return `false`.
+
+**Notes**:
+
+- `'a'`, `'e'`, `'i'`, `'o'`, `'u'`, and their uppercases are **vowels**.
+- A **consonant** is an English letter that is not a vowel.
+
 
 **Example 1:**
 
 ```
-Input: a = "11", b = "1"
-Output: "100"
+Input: word = "234Adas"
+
+Output: true
+
+Explanation:
+
+This word satisfies the conditions.
 ```
