How Can Recursion Affect Space Complexity in Linear Data Structures like Lists?

Recursion is a way of solving problems by having a function call itself. This approach can cause memory issues when used with simple data structures like lists. Here’s why:

  • Stack Frames: Every time a function calls itself, it adds something called a stack frame. This takes up space in memory.
  • Base Case Issues: If there are problems with the base case (the stopping condition for the recursion), it can use even more resources than necessary.

For example, if a function makes nn recursive calls, it might need O(n)O(n) space. This can slow things down and make the program less efficient.

What you can do:

  • Use loops instead of recursion to save memory space.
  • If possible, use a technique called tail recursion optimization. This helps your code run more efficiently without using too much memory.
