查看“︁Scala:模式匹配”︁的源代码

据说模式匹配很强大，可惜还没学会...来个裴波拉切数列吧...

<source lang="scala">
    def main(args: Array[String]) = {
        for (i <- 0 to 10)
            print(fib(i) + " ")
    }

    def fib(n: Int): Int = n match {
        case 0 => 0
        case 1 => 1
        case _ => fib(n - 2) + fib(n - 1)
    }
</source>

<pre>
0 1 1 2 3 5 8 13 21 34 55 
</pre>
