{ "data": { "question": { "questionId": "2011", "questionFrontendId": "1881", "boundTopicId": null, "title": "Maximum Value after Insertion", "titleSlug": "maximum-value-after-insertion", "content": "

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.

\n\n

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.

\n\n\n\n

Return a string representing the maximum value of n​​​​​​ after the insertion.

\n\n

 

\n

Example 1:

\n\n
\nInput: n = "99", x = 9\nOutput: "999"\nExplanation: The result is the same regardless of where you insert 9.\n
\n\n

Example 2:

\n\n
\nInput: n = "-13", x = 2\nOutput: "-123"\nExplanation: You can make n one of {-213, -123, -132}, and the largest of those three is -123.\n
