2598 - Smallest Missing Non-negative Integer After Operations.

Medium

You are given a 0-indexed integer array nums and an integer value.

In one operation, you can add or subtract value from any element of nums.

• For example, if nums = [1,2,3] and value = 2, you can choose to subtract value from nums[0] to make nums = [-1,2,3].

The MEX (minimum excluded) of an array is the smallest missing non-negative integer in it.

• For example, the MEX of [-1,2,3] is 0 while the MEX of [1,0,3] is 2.

Return the maximum MEX of nums after applying the mentioned operation any number of times.

Example 1:

Input: nums = [1,-10,7,13,6,8], value = 5

Output: 4

Explanation:

One can achieve this result by applying the following operations:

• Add value to nums[1] twice to make nums = [1, 0 ,7,13,6,8]

• Subtract value from nums[2] once to make nums = [1,0, 2 ,13,6,8]

• Subtract value from nums[3] twice to make nums = [1,0,2, 3 ,6,8]

The MEX of nums is 4. It can be shown that 4 is the maximum MEX we can achieve.

Example 2:

Input: nums = [1,-10,7,13,6,8], value = 7

Output: 2

Explanation:

One can achieve this result by applying the following operation:

• subtract value from nums[2] once to make nums = [1,-10, 0 ,13,6,8]

The MEX of nums is 2. It can be shown that 2 is the maximum MEX we can achieve.

Constraints:

• 1 <= nums.length, value <= 105
• -109 <= nums[i] <= 109
