- What is recursion and when should I use it? - Stack Overflow
Don't use recursion for factorials or Fibonacci numbers One problem with computer-science textbooks is that they present silly examples of recursion The typical examples are computing a factorial or computing a Fibonacci sequence Recursion is a powerful tool, and it's really dumb to use it in either of those cases
- What is the maximum recursion depth, and how to increase it?
It is a guard against a stack overflow, yes Python (or rather, the CPython implementation) doesn't optimize tail recursion, and unbridled recursion causes stack overflows You can check the recursion limit with sys getrecursionlimit: import sys print(sys getrecursionlimit()) and change the recursion limit with sys setrecursionlimit:
- java - What is recursion - Stack Overflow
A method can call itself, this is recursion Recursive implementations of methods are often used, because they lead to compact elegant code, which is easier to understand than a coresponding implementation that does not use recursion The recursive programming technic knows three important rules (of thumb): Base case: The recursion has a base
- recursion - Recursive vs non-recursive - Stack Overflow
Mostly recursion is better (when it actually is) because it makes an implementation much simpler and less error-prone, and errors are by far the biggest cost in computing (But of course improperly done it can cost you big time as well ) When recursion is good it's very good When recursion is bad it's very bad
- How to understand the concept of recursion in java?
Personally, I do not like the factorial problem I find it hard to understand and I do not think it explains recursion in a clear way So lets look at a different example Lets say that we want to print numbers from 1-100 This is a very simple task with a for loop and a counter, but it can also be done with recursion For example:
