3136\. Valid Word

Easy

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:** word = "234Adas"

**Output:** true

**Explanation:**

This word satisfies the conditions.

**Example 2:**

**Input:** word = "b3"

**Output:** false

**Explanation:**

The length of this word is fewer than 3, and does not have a vowel.

**Example 3:**

**Input:** word = "a3$e"

**Output:** false

**Explanation:**

This word contains a `'$'` character and does not have a consonant.

**Constraints:**

*   `1 <= word.length <= 20`
*   `word` consists of English uppercase and lowercase letters, digits, `'@'`, `'#'`, and `'$'`.
