# Go - Recursion

Recursion is simply the system of rehashing contraptions in a self-comparative way. The equivalent idea applies in programming dialects as pleasantly.
```

func recursion()

recursion()/* trademark calls itself */

func principal()

recursion()

```
The Go programming language bolsters recursion. That is, it allows a trademark to call itself.

## Examples of Recursion in Go

Recursive capacities are helpful to tackle numerous scientific inconveniences comprising of figuring factorial of an assortment of, creating a Fibonacci arrangement, and numerous others.

### Example 1: Calculating Factorial Using Recursion in Go

The accompanying model computes the factorial of a given wide assortment utilizing a recursive trademark
```

bundle key

import "fmt"

func factorial(i int)int

if(i <= 1)

return 1

return I * factorial(i - 1)

func key()

var I int = 15

fmt.Printf("Factorial of %d will be %d", I, factorial(i))

```

## Example 2: Fibonacci Series Using Recursion in Go

```

group principle

import "fmt"

func fibonaci(i int) (ret int)

on the off chance that I == zero

return zero

on the off chance that I == 1

return 1

return fibonaci(i-1) + fibonaci(i-2)

func central()

var I int

for I = zero; I < 20; i++

fmt.Printf("%d ", fibonaci(i))

```
```
