What is the time complexity of removing at index n in an unsorted array?
Question
What is the time complexity of removing at index n in an unsorted array?
Solution
The time complexity of removing an element at a specific index in an unsorted array is O(1) for the removal itself. However, since arrays are contiguous blocks of memory, you would need to shift all the elements after the removed element to fill the gap, which takes O(n) time. Therefore, the overall time complexity is O(n).
