为什么mathematica计算单元运算不出结果

Question

如题所述

Answer 1

include <iostream>
#include <stdio.h>
int jc(int m){
if(m!=1) return m*jc(m-1);
else return 1;
}
int c(int m,int n){
if(m>=n) return jc(m)/(jc(n)*jc(m-n));
}
int main(void){
int m,n;
scanf("%d%d",&m,&n);
printf("%d\n",c(m,n));
return 0;

Answer 2

代码如下：
pu; pu1 = -pu + \[ImaginaryJ]*pu; pu2 = -pu - \[ImaginaryJ]*pu;
\[Beta]0 =
pu1*pu2; \[Beta]1 = -(pu1 + pu2); \[Delta]0 = -pu3*pu4*
pu5; \[Delta]1 =
pu3*pu4 + pu3*pu5 + pu4*pu5; \[Delta]2 = -(pu3 + pu4 + pu5);
