Leetcode Solutions

One Pass with Two Pointers

  1. Initialize an empty list res to store the k-distant indices.
  2. Initialize pointer j to 0 to keep track of the last index added to res.
  3. Iterate through the array nums using pointer i.
  4. When nums[i] equals key, perform the following steps: a. Update j to be the maximum of j and i - k. b. While j is less than or equal to i + k and less than the length of nums, add j to res and increment j.
  5. Return the list res.
