f(n)=(3n-1)(n)/2=3n²/2-n/2
试试下面这个#includevoidmain(void){doublefunc(int);doubles=0,term;inti;for(i=0,term=1;;i++){term=1.
#includedoublefact(intn){doubles=1.0;inti;for(i=1;i
#include"stdio.h"doublef(int){if(n>0);doublem=0.0;for(inti=0;i
publicclassTest{ publicstaticvoidmain(String[]args){ doublen=10; doubleresult=fmethod(n); System
a=a+1.0/tota(n);
#includeusingnamespacestd;intpow(intx,intn){if(n==0)return1;elsereturnpow(x,n-1)*x;}voidmain(){intx,
inttotal(intn){returnfact(n);}intfact(intn){if(n==1)return1;elsereturnn+fact(n-1);}
vars,ans:int64;i:longint;beginreadln(s);fori:=1tosdoinc(ans,facto(i));writeln(ans);end.也许需要高精度!当s>=1
#include "stdio.h"int total(int n){ int sum=0; i
intsun=1;//计算阶乘的值intsum=0;//累加for(inti=0;i
C描述functionttt(n){ returnn>1?n*ttt(n-1):1;}使用方法:ttt(21);
doublefact(intn){doubletemp;if(n==0||n==1)return1.0;if(n>=2){temp=double(n*fact(n-1));rentuntemp;}}
#includeintmain(){intn;doublem;doublefac(intn);scanf("%d",&n);m=fac(n);printf("%d!=%f\n",n,m);return
publicinttotal(intn){intresult=0;for(inti=1;i
//阶乘函数intfactorial(intn){if(n>n;ints=1;while(n>1){s+=1/factorial(n--);}cout
