public class Solution extends Object
1881 - Maximum Value after Insertion\. Medium You are given a very large integer `n`, represented as a string, and an integer digit `x`. The digits in `n` and the digit `x` are in the **inclusive** range `[1, 9]`, and `n` may represent a **negative** number. You want to **maximize** `n` **'s numerical value** by inserting `x` anywhere in the decimal representation of `n`. You **cannot** insert `x` to the left of the negative sign. * For example, if `n = 73` and `x = 6`, it would be best to insert it between `7` and `3`, making `n = 763`. * If `n = -55` and `x = 2`, it would be best to insert it before the first `5`, making `n = -255`. Return _a string representing the **maximum** value of_ `n`_ after the insertion_. **Example 1:** **Input:** n = "99", x = 9 **Output:** "999" **Explanation:** The result is the same regardless of where you insert 9. **Example 2:** **Input:** n = "-13", x = 2 **Output:** "-123" **Explanation:** You can make n one of {-213, -123, -132}, and the largest of those three is -123. **Constraints:** * 1 <= n.length <= 105 * `1 <= x <= 9` * The digits in `n` are in the range `[1, 9]`. * `n` is a valid representation of an integer. * In the case of a negative `n`, it will begin with `'-'`.
