简单题，好久没写c++代码了，练习zoj，也学习c++.

 

#include <iostream>#include <cmath>using namespace std;const int ROW = 8;const int COLUMN = 6;char abacus[ROW][COLUMN];int main(){int cas;cin >> cas;int start;int end;int sum;while(cas--){cin >> start >> end;sum = 0;for(int i = start; i <= end; i++){sum += i;}for(int i = 0; i < ROW; i++){for(int j = 0; j < COLUMN; j++){cin >> abacus[i][j];}}int getSum = 0;int times = 1;for(int i = COLUMN - 1; i >= 0; i--){int thisSum = 0;if(abacus[0][i] == '|'){thisSum = 5;}for(int j = 3; j < ROW; j++){if(abacus[j][i] == '|'){thisSum += (j - 3);break;}}getSum += thisSum * times;thisSum = 0;times *= 10;}if(sum == getSum){cout << "No mistake" << endl;}else{cout << "Mistake" << endl;}}}
