用递归的思路完成 1 2 ... 100java

#include"stdio.h"intgys(intm,intn){if(n>1){if(m%n!=0){returngys(n,m%n);}elsereturnn;}}intmain(){intm

可以用while?如果可以就简单了.如果任何条件都不许用,参考下面的链接

PrivateSubForm_load()DimiAsLong,nasintegern=int(val(inputbox("输入Fibonacci数列的项数")))Fori=1TonPrintFibo

varn:integer;functionfac(n:integer):longint;beginifn

代码如下:OptionExplicitPrivateSubCommand1_Click()MsgBoxP(2,2)EndSubFunctionP(ByValnAsInteger,ByValxAsDou

longfac(int);这一步应该为longfac(int,float);y=fac(n);这一步应该为：y=fac(n,x);elseif(n=0)f=1;这一步应该为：elseif(n==0)f

第1次:factorial(5)sum+=5*factorial(4)第2次:factorial(4)sum+=4*factorial(3)第3次:factorial(3)sum+=3*factori

longfib(intn)　　{　　if(n==0)return0;　　if(n==1)return1;　　if(n>1)returnfib(n-1)+fib(n-2);　　}

你先了解这个函数的作用,结果就是n*(n/(2^1)*(n/(2^2))*(n/(2^3))*(n/(2^4))……*1n*(n/2)*(n/4)*(n/8)*……*1while(n>=0){if(n
