题目链接如下:
我的代码如下:
- #include

-
- int w, h;
- std::vector
int, int>> vec; -
- bool cmp(const std::pair<int, int> &a, const std::pair<int, int> &b){
- return a.first != b.first ? a.first > b.first : a.second > b.second;
- }
-
- int main(){
- while(scanf("%d %d", &w, &h) == 2){
- vec.clear();
- for(int i = 0; i < 6; ++i){
- if(i != 0){
- scanf("%d %d", &w, &h);
- }
- if(w < h){
- std::swap(w, h);
- }
- vec.push_back({w, h});
- }
- sort(vec.begin(), vec.end(), cmp);
- if(vec[1] != vec[0] || vec[2] != vec[3] || vec[4] != vec[5] || vec[0].first != vec[2].first || vec[0].second != vec[4].first || vec[2].second != vec[4].second){
- printf("IMPOSSIBLE\n");
- continue;
- }
- printf("POSSIBLE\n");
- }
- return 0;
- }
