唉……我真的挂在大树上了,求破解!各种情况都考虑了……

//下面是我的源代码 WA了……

#include<iostream>
#include<string>
using namespace std;
int a0[41] = {0};         //我准备用整数数组存储,1个存5位,这样一共有205位,绝对够了……
void add(int*sum1,int*sum2){        //add up
	int add = 0;
        //这句貌似没有必要,但有备无患吧
	memset(a0,0,41*sizeof(int));
	for(int i = 40;i >= 0;--i){
		if(sum1[i] == 0 && sum2[i] == 0 && add == 0)break;
		a0[i] = sum1[i] + sum2[i] + add;
		add = a0[i]/100000;
		a0[i] %= 100000;
	}
}
int expo(int n){        //calculate value: 10^n
	int i = 1;
	for(int j = 0;j < n;++j)i*=10;
	return i;

	printf("\n");
}

        //sum1用于记录当前的和,再与sum2相加
	int sum1[41] = {0},sum2[41] = {0};
	input(sum1);
	if(sum1[40] == 0){     //连没有输入的情况都考虑了!真无语……
		printf("0\n");
