Leetcode 1848. Minimum Distance to the Target Element

Input: nums = [1,2,3,4,5], target = 5, start = 3
Output: 1
Explanation: nums[4] = 5 is the only value equal to target, so the answer is abs(4 - 3) = 1.
Input: nums = [1], target = 1, start = 0
Output: 0
Explanation: nums[0] = 1 is the only value equal to target, so the answer is abs(0 - 0) = 1.
Input: nums = [1,1,1,1,1,1,1,1,1,1], target = 1, start = 0
Output: 0
Explanation: Every value of nums is 1, but nums[0] minimizes abs(i - start), which is abs(0 - 0) = 0.
  • 1 <= nums.length <= 1000
  • 1 <= nums[i] <= 104
  • 0 <= start < nums.length
  • target is in nums.
  1. check all the nums and if the nums[i] equals to target, check it’s absoulte gap.
