请问家人们用c语言怎么解？

#include<iostream>
#include<cstdlib>
#include<string>
#include<cstring>
#include<cstdio>
#include<algorithm>
#include<climits>
#include<cmath>
#include<cctype>
#include<stack>
#include<queue>
#include<list>
#include<vector>
#include<set>
#include<map>
#include<sstream> 
#include<unordered_map>
using namespace std;
 
typedef long long LL;
 
const int inf=0x3f3f3f3f;
 
const int N=1e5+100;
 
int main()
{
//  freopen("input.txt","r",stdin);
    int n;
    scanf("%d",&n);
    int mmax=0;
    int ans=0;
    for(int i=1;i<=n;i++)
    {
        int num;
        scanf("%d",&num);
        mmax=max(mmax,num);
        if(ans==0)
            ans=num;
        else
            ans=__gcd(ans,num);
    }
    mmax/=ans;
    if((mmax-n)&1)
        printf("Alice\n");
    else
        printf("Bob\n");
    
    
    
    
    
    
    
    
    
    return 0;
}
