ZOJ-1175

比较水的模拟，注意读题，input虽然分行给出，但实际是要连在一起处理的，换行符去掉，空格要保留，然后按题意处理完输出时，注意每80个字符换行

#include<cstdio>#include<vector>#include<deque>#include<algorithm>using namespace std;int main(){int N;scanf("%d", &N);vector<char> res;deque<char> source;for (int t = 0; t < N; t++){if (t)putchar('\n');int n;scanf("%d", &n);getchar();char c;res.clear();source.clear();while (n--)while ((c = getchar()) != '\n')source.push_back(c);bool forward = true;while ((c = getchar()) != '#'){if (c == 'R')forward = !forward;if (c == 'G'){if (forward){res.push_back(source.front());source.pop_front();}else{res.push_back(source.back());source.pop_back();}}}size_t i;for (i = 0; i < res.size(); i++){putchar(res[i]);if ((i + 1) % 80 == 0)putchar('\n');}if (i % 80)putchar('\n');}return 0;}
