2216. Minimum Deletions to Make Array Beautiful

Leetcode Solutions

Greedy Approach with Even Index Tracking

  1. Initialize a counter deletions to 0 to track the number of deletions needed.
  2. Iterate through the array using an index i starting from 0.
  3. For each even index i, check if nums[i] is equal to nums[i + 1].
  4. If they are equal, increment the deletions counter and skip the next element by incrementing i.
  5. After the loop, check if the length of the array minus the number of deletions is odd.
  6. If it is odd, increment deletions by 1 to ensure the final array has an even length.
  7. Return the deletions counter as the result.
