# What is difference between recursive and iterative?

## What is difference between recursive and iterative?

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.

## Is recursive or iterative better?

The fact is that recursion is rarely the most efficient approach to solving a problem, and iteration is almost always more efficient. This is because there is usually more overhead associated with making recursive calls due to the fact that the call stack is so heavily used during recursion.

Why we should not use recursion?

However, in most of the circumstances, recursive functions have very high complexity that we should avoid using. One of the much better solutions is to use Dynamic Planning when possible, which is probably the best way to solve a problem that can be divided into sub-problems.

What is the advantage of recursion?

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.

### Is recursion good or bad?

Recursion is a useful technique for making code terse and comprehensible. However, it is less performant and breeds stack overflow exceptions in non tail call optimized languages. Carefully scrutinize your use case when choosing between recursive and iterative functions.

### What is the difference between recursion and iteration?

The iteration is when a loop repeatedly executes until the controlling condition becomes false. The primary difference between recursion and iteration is that is a recursion is a process, always applied to a function. The iteration is applied to the set of instructions which we want to get repeatedly executed.

What are the advantages of recursion compared to iteration?

The following interrelated advantages of recursion can be distinguished: the naturalness of the presentation of seemingly complex algorithms; recursive algorithm is more readable in comparison with iterative; for many common tasks, recursion is easier to implement than iteration. Recursion is well suited for implementing list traversal algorithms, trees, expression parsers, combinatorial tasks etc.

Is it better to use recursive or loops?

Recursion is not intrinsically better or worse than loops-each has advantages and disadvantages, and those even depend on the programming language (and implementation).

## Can every recursive function be made iterative?

Yes, every recursive function can be converted to an iterative one by following a rather mechanical process. Recall that compilers implement recursion by using a stack, which is typically implemented in the CPU’s hardware.
