发射!

"爆炸之前"的数字!应该是前10个斐波那契数字.我的源代码如下.

    public class Fibonacci {

  public static long fib(int n) {
    if (n <= 1) return 1;
    return fib(n-1) + fib(n-2);
  }

  public static long fastfib(int n) {
    int a = 0;
    int b = 1;
    int c = 0;

    for (int i = 0; i <= n; n++) {
      c = a + b;
      a = b;
      b = c;    
    }

    return c;
  }

}

并且实现fastfib方法的类是:
