Questions & Step-by-Step Solutions
What is the average time complexity for inserting an element at the end of a dynamic array?
Step 1: Understand what a dynamic array is. A dynamic array is a data structure that can grow in size when needed.
Step 2: Know that inserting an element at the end of a dynamic array is usually very fast, which is called O(1) time complexity.
Step 3: Realize that sometimes, when the dynamic array is full, it needs to be resized to make more space for new elements.
Step 4: Understand that resizing the array takes longer, specifically O(n) time complexity, because all existing elements need to be copied to the new larger array.
Step 5: Conclude that on average, considering both cases, the time complexity for inserting an element at the end of a dynamic array is O(1).
