Questions & Step-by-Step Solutions

What is the worst-case time complexity of inserting an element into a linked list?
  • 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: Know that to insert an element, you need to find the right place in the list.
  • Step 3: In the worst case, you may have to look at every node in the list to find where to insert the new element.
  • Step 4: If there are 'n' nodes in the list, this means you might have to check all 'n' nodes.
  • Step 5: Therefore, the time it takes to insert an element in the worst case is proportional to the number of nodes, which is O(n).
