题目描述

编写一个求斐波那契数列的递归函数,输入n 值,使用该递归函数,输出如下图形(参见样例)。

输入

输入第一行为样例数m,接下来有m行每行一个整数n,n不超过10。

输出

对应每个样例输出要求的图形(参见样例格式)。

样例输入

16

样例输出

0        0 1 1      0 1 1 2 3    0 1 1 2 3 5 8  0 1 1 2 3 5 8 13 210 1 1 2 3 5 8 13 21 34 55

思想:什么是递归?要理解递归,你要先理解递归,直到你能理解递归。

#include 
#include
using namespace std;int f(int n){ if(n==1||n==2) return 1; else if(n==0) return 0; else return f(n-1)+f(n-2);}int main(){ int m,n,i,j,k,x; cin >>m; for(i=0;i
>n; for(j=0;j
