Questions & Step-by-Step Solutions

What is a key advantage of using linked lists over arrays?
  • Step 1: Understand what a linked list is. A linked list is a data structure where each element (node) points to the next one.
  • Step 2: Understand what an array is. An array is a collection of elements stored in a fixed-size format.
  • Step 3: Know that arrays have a fixed size. Once you create an array, you cannot change its size without creating a new one.
  • Step 4: Learn that linked lists can grow or shrink in size. You can add or remove elements without needing to create a new list.
  • Step 5: Realize that this flexibility in size makes linked lists more efficient when you don't know how many elements you will need in advance.
