Is Recursion Hard to Learn?

Recursion is not hard, whereas thinking recursively might be confusing in some cases. The recursive algorithm has considerable advantages over identical iterative algorithm such as having fewer code lines and reduced use of data structures.

How long does it take to understand recursion?

However, the exact concept of recursion does not take more than a few minutes to understand. (“few” ranging from about 1 to 50 here, loosely speaking). In fact, I did not meet anyone who struggled with the basic applications of recursion.

Is recursion harder than iteration?

" using Iteration is: " . ... Time Complexity: Finding the Time complexity of Recursion is more difficult than that of Iteration. Recursion: Time complexity of recursion can be found by finding the value of the nth recursive call in terms of the previous calls.
