LeetCode Remove Duplicates from Sorted Array in Java
In this tutorial, we'll tackle a common coding interview question: removing duplicates from a sorted array such that each unique element appears at most twice. We'll implement a solution in Java using a two-pointer technique, ensuring an efficient and in-place operation with O(1) extra memory.
We'll walk through the problem step-by-step:
Understanding the problem and constraints.
Developing the algorithm using a two-pointer approach.
Writing the Java code to implement the solution.
Verifying the solution with a sample input.
By the end of this video, you'll have a solid grasp of how to solve this problem efficiently, a key skill for technical interviews and coding challenges.
Example Input and Output:
Input: [1, 1, 1, 2, 2, 3]
Output: k = 5, nums = [1, 1, 2, 2, 3, _]
