WebIt is hard to understand especially when the number of recursive calls (sequential) is more than one. For some programs, it takes really long to run. For example, the recursive solution of Fibonacci number is way slower than its iterative counterpart. So, try to avoid recursion as much as possible when you are doing simple programs. WebAfter all, recursion suffers from function call overhead, which in the example above could be substantial compared to the operation inside the function itself. So the whole reason to do recursion rather than iteration should be to take advantage of the …
