2453. Destroy Sequential Targets
Medium
30 Points
Array
Hash Table
Counting
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.
Examples
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
