You are given an integer num. You can swap two digits at most once to get the maximum valued number.

\n\n

Return the maximum valued number you can get.

\n\n

 

\n

Example 1:

\n\n
\nInput: num = 2736\nOutput: 7236\nExplanation: Swap the number 2 and the number 7.\n
\n\n

Example 2:

\n\n
\nInput: num = 9973\nOutput: 9973\nExplanation: No swap.\n
\n\n

 

\n

Constraints:

\n\n\n", "translatedTitle": "最大交换", "translatedContent": "

给定一个非负整数，你至多可以交换一次数字中的任意两位。返回你能得到的最大值。

\n\n

示例 1 :

\n\n
\n输入: 2736\n输出: 7236\n解释: 交换数字2和数字7。\n
\n\n

示例 2 :

\n\n
\n输入: 9973\n输出: 9973\n解释: 不需要交换。\n
\n\n

注意:

\n\n
    \n\t
  1. 给定数字的范围是 [0, 108]
    2. \n
