改写下列代码为判断点p在result中出现的次数stdunordered_mapint int countMap6; for const auto& edge result countMap6edgesrc++; countMap6edgetgt++; int begin = 0; for const auto& pair1 countMap6

std::unordered_map<int, int> countMap6; for (const auto& edge : result) { countMap6[edge.src]++; countMap6[edge.tgt]++; } int pCount = countMap6[p]; std::cout << "点p出现 " << pCount << " 次" << std::endl;
