In which situation would you recommend the use of recursive function over an iteration?

If time complexity is the point of focus, and number of recursive calls would be large, it is better to use iteration. However, if time complexity is not an issue and shortness of code is, recursion would be the way to go.

At what circumstances you would like to prefer recursive function?

When should I use recursion? Recursion is made for solving problems that can be broken down into smaller, repetitive problems. It is especially good for working on things that have many possible branches and are too complex for an iterative approach. One good example of this would be searching through a file system.

Why is iterative solution better than recursive?

An Iterative algorithm will be faster than the Recursive algorithm because of overheads like calling functions and registering stacks repeatedly. Many times the recursive algorithms are not efficient as they take more space and time.

In which circumstances recursion function is called?

MCQ: In which circumstances the recursion function is called? To solve a problem. For calling maths function. To calling input and output stream. All of them.

What are the advantages of recursive function?

Advantages of Recursion For a recursive function, you only need to define the base case and recursive case, so the code is simpler and shorter than an iterative code. Some problems are inherently recursive, such as Graph and Tree Traversal.

What is difference between iterative and recursive?

The concept of Recursion and Iteration is to execute a set of instructions repeatedly. The key difference between recursion and iteration is that recursion is a process to call a function within the same function while iteration is to execute a set of instructions repeatedly until the given condition is true.

What is the difference between recursive and non-recursive function?

Answer: Recursive function is a function which calls itself again and again. A recursive function in general has an extremely high time complexity while a non-recursive one does not. A recursive function generally has smaller code size whereas a non-recursive one is larger.

Is iterative more efficient than recursive?

In terms of assembly code, iterative represent less instruction, and thus, it is much more performant than the recursive ones. On the other hand, modern compiler leverage recursive optimization to optimized recursive computation to be the same performant as iterative solutions.

What is recursion explain with suitable example?

Recursion is the process of defining a problem (or the solution to a problem) in terms of (a simpler version of) itself. For example, we can define the operation “find your way home” as: If you are at home, stop moving. Take one step toward home. “find your way home”.

What are the advantages and disadvantages of using recursive functions?

Advantages/Disadvantages of Recursion #

• To solve such problems which are naturally recursive such as tower of Hanoi.
• Reduce unnecessary calling of function.
• Extremely useful when applying the same solution.
• Recursion reduce the length of code.
• It is very useful in solving the data structure problem.

What is the difference between recursive and non recursive functions give their merits and demerits?

Recursive function is a function which calls itself again and again. A recursive function in general has an extremely high time complexity while a non-recursive one does not. A recursive function generally has smaller code size whereas a non-recursive one is larger.

What is the difference between iterative and recursive DNS queries?

A recursive DNS lookup is where one DNS server communicates with several other DNS servers to hunt down an IP address and return it to the client. This is in contrast to an iterative DNS query, where the client communicates directly with each DNS server involved in the lookup.

What is the difference between recursion and iterative function?

Recursive function call itself while does not reach the out poin whereas iterative function update calculating value through the iteration over the range. To those who might still want to see the difference between recursive and iterative function. Thanks for contributing an answer to Stack Overflow!

Should I use iteration or recursion to solve a problem?

Please Sign up or sign in to vote. In the majority of cases iteration is by far more efficient (in terms of execution time and memory resources) than recursion. So the simple rule is: If you can solve a problem by iteration without making the code overly complex, then stick to iteration.

Can recursion be used as a loop?

Every recursion can be modeled as a kind of loop, that’s what the CPU will ultimately do. And the recursion itself, more directly, means putting the function calls and scopes in a stack. But changing your recursive algorithm to a looping one might need a lot of work and make your code less maintainable.

When should I use iteration instead of function call?

So the simple rule is: If you can solve a problem by iteration without making the code overly complex, then stick to iteration. The reason for iteration being generally more efficient is that in general the cost of a loop construct is lower than a function call.
