This question is very skillful in reading data. It is just like reading data with scanf, and then converting the number of reads into a 10-digit system according to the base system.

`#include<cstdio>#include<cstring>#include<cctype>using namespace std;int main(){    //freopen("in.txt","r",stdin);    int cas,base,num1,num2;    char str1[50],str2[50];    scanf("%d",&cas);    while(cas--)    {        scanf("%s %s %d",str1,str2,&base);        num1=num2=0;        for(int i=0; str1[i]!='\0'; i++)        {    int a;            if(isalpha(str1[i]))            a=str1[i]-'a'+10;            else a=str1[i]-'0';            num1=num1*base+a;        }        for(int i=0; str2[i]!='\0'; i++)        {            int a;             if(isalpha(str2[i]))            a=str2[i]-'a'+10;            else a=str2[i]-'0';            num2=num2*base+a;        }        printf("(%d,%d)\n",num1/num2,num1%num2);    }    return 0;}`
