Questions & Step-by-Step Solutions

What is the space complexity of a recursive function that uses a linked list to store n elements?
  • Step 1: Understand what space complexity means. It refers to the amount of memory space required by an algorithm as a function of the input size.
  • Step 2: Identify the data structure used in the function. In this case, it is a linked list.
  • Step 3: Recognize that a linked list stores elements in nodes, where each node contains data and a reference to the next node.
  • Step 4: Determine how many elements are stored in the linked list. Here, it is stated that there are n elements.
  • Step 5: Conclude that since each of the n elements requires space in the linked list, the total space used is proportional to n.
  • Step 6: Therefore, the space complexity of the recursive function that uses a linked list to store n elements is O(n).
