用递归调用求斐波那契数列的第n项

#includeunsignedintFibonacci(intn);intmain(void){inti;for(i=1;i

添加一个文本框输入前N项的N值,再添加一个命令按钮即可PrivateFunctionF(NAsLong)AsLongIfN>2ThenF=F(N-1)+F(N-2)ElseF=1EndIfEndFun

他的代码return1,是指序列从1开始,1,1,2,3,从0开始的话,改成if(k==0)return0;elseif(k==1)return1;elsereturnfib(k-1)+fib(k-2

帮你写好了.unsigned int fib(unsigned int n) {\x09if (n == 1
