    2453 - Destroy Sequential Targets.

    Medium

    You are given a 0-indexed array nums consisting of positive integers, representing targets on a number line. You are also given an integer space.

    You have a machine which can destroy targets. Seeding the machine with some nums[i] allows it to destroy all targets with values that can be represented as nums[i] + c * space, where c is any non-negative integer. You want to destroy the maximum number of targets in nums.

    Return the minimum value of nums[i] you can seed the machine with to destroy the maximum number of targets.

    Example 1:

    Input: nums = [3,7,8,1,1,5], space = 2

    Output: 1

    Explanation: If we seed the machine with nums[3], then we destroy all targets equal to 1,3,5,7,9,… In this case, we would destroy 5 total targets (all except for nums[2]). It is impossible to destroy more than 5 targets, so we return nums[3].

    Example 2:

    Input: nums = [1,3,5,2,4,6], space = 2

    Output: 1

    Explanation: Seeding the machine with nums[0], or nums[3] destroys 3 targets. It is not possible to destroy more than 3 targets. Since nums[0] is the minimal integer that can destroy 3 targets, we return 1.

    Example 3:

    Input: nums = [6,2,5], space = 100

    Output: 2

    Explanation: Whatever initial seed we select, we can only destroy 1 target. The minimal seed is nums[1].

    Constraints:

    • 1 <= nums.length <= 105
    • 1 <= nums[i] <= 109
    • 1 <= space <= 109
