            priority_queue<int, vector<int>, greater<>> pq = priority_queue<int, vector<int>, greater<>>();
            int n;
            cin >> n;
            int x;
            while(n--) {
                cin >> x;
                pq.push(x);
            }
            int ans = 0;
            while(pq.size() > 1) {
                int a = pq.top();
                pq.pop();
                int b = pq.top();
                pq.pop();
                ans += a + b;
                pq.push(a + b);
            }
            cout << ans;
            return 0;
        }

被这些函数引用 TEST().

◆ TEST()

acwing::acwing148::TEST	(	acwing148	,
		case1
	)

                               {
            istringstream in("3 \n"
                             "1 2 9 ");
            auto out = ostringstream();
            main(in, out);
            const auto ans = out.str();
            ASSERT_EQ("15", ans);
        }

引用了 main().
