CodeChef 问题：最小最大

Question

I can't seem to understand why this code isn't yielding the correct answer on CodeChef. When I run it on my machine. Seems to yield the correct cost

Problem Link: https://www.codechef.com/problems/MNMX

using namespace std;

int main()
{
   unsigned int T, N, cost,element,del;
   std::cout<<"Enter the Test Cases";
   std::cin>>T;
   for (unsigned int i=0;i<T;i++){

        std::cout<<"Enter the size of the array";
        std::cin>>N;
        std::cout<<"Enter the values for "<<i+1<<" Test Case"<<endl;
        vector<int> first;
        std::cout<<"enter the values of the array"<<endl;
    for (unsigned int i=0;i<N;i++){
        std::cin>>element;
        first.push_back(element);
    }

   if (N>1){
    for (unsigned int i=0;i<N;i++){
        element = 0;
       element = min (first.front() , first[1]);
       del = max (first.front() , first[1]);
       first.erase(std::remove(first.begin(), first.end(), del), first.end());
        first.push_back(element);


   }
   }
   cost = first.front();
   std::cout<<"Cost: "<<cost<<endl;

}
return 0;
}

Answer 1

Generally this kind of test cases will not allow your logs to be part of this so please remove all cout statement except last, which you can modify like

std::cout << cost << std::endl;

Try this on codechef.

Or just edit last main output line as above.

Answer 2

尝试在 for 循环中使用不同的迭代器变量，例如 j 和 k 用于内部循环。
