| Go supports <a href="http://en.wikipedia.org/wiki/Recursion_(computer_science)"><em>recursive functions</em></a>. Here's a classic factorial example. | ||
package main |
||
import "fmt" |
||
| This `fact` function calls itself until it reaches the base case of `fact(0)`. | func fact(n int) int { |
|
if n == 0 { |
||
return 1 |
||
} |
||
return n * fact(n-1) |
||
} |
||
func main() { |
||
fmt.Println(fact(7)) |
