Leetcode Solutions

Two-Pointer Approach for Doubling and Shifting

  1. Iterate through the array from index 0 to n - 2.
  2. If nums[i] is equal to nums[i + 1], double nums[i] and set nums[i + 1] to 0.
  3. Initialize two pointers, nonZeroIndex and currentIndex. Set both to 0.
  4. Iterate through the array with currentIndex.
  5. If nums[currentIndex] is not zero, swap nums[currentIndex] with nums[nonZeroIndex] and increment nonZeroIndex.
  6. Increment currentIndex.
  7. Continue until currentIndex reaches the end of the array.
  8. Return the modified array.
