输出需要排序，给你个C++的代码，看最后排序的就好 #include <iostream> #include <algorithm> #include <vector> using namespace std; class Bear { public: int capacity; int hungry; int num; }; bool myGreater(const Bear &a, const Bear &b) { if (a.capacity > b.capacity) return true; return false; } bool myGreaterI(const Bear &a, const Bear &b) { if (a.num < b.num) return true; return false; } void printBear(const Bear &a) { cout << a.capacity << " " << a.hungry << endl; } int eat(vector<int> &v, Bear &a) { if (a.hungry <= 0) return 0; for (int i = v.size() - 1; i >= 0; i--) { if (v[i] <= a.hungry) { a.hungry = a.hungry - v[i]; v.erase(v.begin() + i); eat(v, a); return 0; } } return 0; } int main() { int n, m; while (cin >> n >> m) { vector<int> mm;//糖能填充的饥饿值 for (int i = 0; i < m; i++) { int temp; cin >> temp; mm.push_back(temp); } Bear *bb = new Bear[n]; for (int i = 0; i < n; i++) { cin >> bb[i].capacity >> bb[i].hungry; bb[i].num = i; } sort(mm.begin(), mm.end(), less<int>()); sort(bb, bb + n, myGreater); for (int i = 0; i < n; i++) { //for (int j = n - 1; j >= 0; j--) { //if eat(mm, bb[i]); } } sort(bb, bb + n, myGreaterI); //for_each(bb, bb + n, printBear); for (int i = 0; i < n; i++) { cout << bb[i].hungry << endl; } delete[] bb; } return 0; }
