Questions & Step-by-Step Solutions
Which of the following operations has a time complexity of O(n) in 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 what time complexity means. Time complexity describes how the time to complete an operation grows as the number of elements (n) increases.
Step 3: Identify the operation we are considering. In this case, we are looking at searching for a value in a linked list.
Step 4: Realize that to find a value, you may need to look at each node in the linked list one by one.
Step 5: Understand that in the worst case, you might have to check every node until you find the value or reach the end of the list.
Step 6: Conclude that since you may have to check all n nodes, the time complexity for searching in a linked list is O(n).
