Java完成计算阶乘fct=m!=1*2*3*-*m,其中的m由用户输入.-搜答案-百度作业网

#includelongfactorial(intm,intn){longsum=1,sum1=1;inti;if(m-n>n){for(i=m;i>m-n;i--)sum*=i;for

简单,程序如下:cleam=0n=0sm=1sn=1s=0@4,4say'inputm'getmread@5,4say'inputn'getnreadfori=1tomsm=sm*iendforfor

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

functionresult=fa(N)result=1;fori=1:Nresult=result*i;end上述N不可太大,否则超过范围Matlab中带有factorial函数球阶乘
