164\. Maximum Gap
Hard
Given an integer array `nums`, return _the maximum difference between two successive elements in its sorted form_. If the array contains less than two elements, return `0`.
You must write an algorithm that runs in linear time and uses linear extra space.
**Example 1:**
**Input:** nums = [3,6,9,1]
**Output:** 3
**Explanation:** The sorted form of the array is [1,3,6,9], either (3,6) or (6,9) has the maximum difference 3.
**Example 2:**
**Input:** nums = [10]
**Output:** 0
**Explanation:** The array contains less than 2 elements, therefore return 0.
**Constraints:**
* 1 <= nums.length <= 105
* 0 <= nums[i] <= 109
