In this lab, you will implement a function called getMinDistance to find the minimum distance to a target element in an array. The function should take an integer array nums (0-indexed) and two integers target and start as input, and return the minimized value of abs(i - start) where nums[i] == target. Note that abs(x) is the absolute value of x.

It is guaranteed that target exists in nums.

Function Signature

/** * @param {number[]} nums * @param {number} target * @param {number} start * @return {number} */ export function getMinDistance(nums, target, start) { }

Examples

Example 1:

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.

Example 2:

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) = 0.

Example 3:

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.

Constraints:

  • 1 <= nums.length <= 1000
  • 1 <= nums[i] <= 104
  • 0 <= start < nums.length
  • target is in nums.

Make sure to export any function, variable, or class you want to test in the evaluation script. The order of try-catch blocks inside the evaluation script must match the order of the challenges.
