482 - License Key Formatting\. Easy You are given a license key represented as a string `s` that consists of only alphanumeric characters and dashes. The string is separated into `n + 1` groups by `n` dashes. You are also given an integer `k`. We want to reformat the string `s` such that each group contains exactly `k` characters, except for the first group, which could be shorter than `k` but still must contain at least one character. Furthermore, there must be a dash inserted between two groups, and you should convert all lowercase letters to uppercase. Return _the reformatted license key_. **Example 1:** **Input:** s = "5F3Z-2e-9-w", k = 4 **Output:** "5F3Z-2E9W" **Explanation:** The string s has been split into two parts, each part has 4 characters. Note that the two extra dashes are not needed and can be removed. **Example 2:** **Input:** s = "2-5g-3-J", k = 2 **Output:** "2-5G-3J" **Explanation:** The string s has been split into three parts, each part has 2 characters except the first part as it could be shorter as mentioned above. **Constraints:** * 1 <= s.length <= 105 * `s` consists of English letters, digits, and dashes `'-'`. * 1 <= k <= 104
