New Driver's License Code

Question

Hi, I made this code using C++ and I tested it on a different app and everything seemed fine. However, running it in the testing environment I get an error that says timeout: the monitored command dumped core. What does this mean? I researched it but I haven't gotten a clear answer as to what I did wrong.

#include <iostream>
#include <string>
#include <sstream>
#include <vector>
#include <algorithm>

using namespace std;

void split_q_string(vector <string> &q, string &qString){
string s_qString;
stringstream split(qString);
while (getline(split, s_qString, ' ')){
q.push_back(s_qString);
}
}

void arrVector(vector <string> &q){
sort(q.begin(), q.end());
}

void printVector(vector <string> &q){
for(int i=0; i<5; i++){
}
}

int calcTime(vector <string> &q,int const &a_num,string const &name){
string odd[3];
string even[3];
int counter=0;
int j=0;
for(int i=0; i<5; i++){
(i%2==0)? even[counter] = q[i] : odd[counter] = q[i];
j++;
if(j%2==0){
counter++;
}
}

for(int i=0; i<3; i++){
if(name==even[i]){
return i;
}
if(name==odd[i]){
return i;
}
}

return -1;
}

int main(){
string name,p_inQueue;
int noAgents, result;

getline(cin,name);
cin>>noAgents;
getline(cin, p_inQueue);

vector <string> QueueList;
split_q_string(QueueList,p_inQueue);

QueueList.push_back(name);

arrVector(QueueList);
printVector(QueueList);
result=calcTime(QueueList,noAgents, name);
result *= 20;
result += 20;
cout<<result;
return 0;
}

P.S I know it's not very efficient right now, but this was my first time doing it as a challenge

Answer 1

While I do not immediately see why it gets a timeout error, I would recommend re-thinking the solution. The code is ambitiously over-designed. It is unnecessary to model the whole operation just to find the answer.

Hint: Count how many names are alphabetically in line ahead of you, then calculate the wait time based on that number. There is no need to sort or use data structures.
