Which of the following operations has the worst time complexity in a singly linked list?
Step 1: Understand what a singly linked list is. It is a data structure where each element (node) points to the next one, and you can only access the first node directly (the head).
Step 2: Identify the operations you can perform on a singly linked list, such as accessing an element, adding an element, or removing an element.
Step 3: Focus on the operation of accessing an element. To access a specific node, you must start at the head and follow the links to reach the desired node.
Step 4: Realize that in the worst case, you may have to traverse the entire list to find the node you want. If there are 'n' nodes in the list, this means you could potentially check each node one by one.
Step 5: Conclude that the time it takes to access an element in a singly linked list is O(n) in the worst case, where 'n' is the number of nodes in the list.
