Can anyone please explain the algorithm in detail…and
provide the code in C…?Here my doubt is …I am scanning the arriving times,departure times and preferred places in three different arrays…if I had sorted anyone of them,I would have lost the connection between three of them…How can I get rid of this…?
Thanks in advance…!!!

You can use struct and sort the whole struct using compare function
e.g.
void comp(struct node a,struct node b)
{
return a.arr < b.arr; //this will sort the structs according to arrival time.
}
struct node
{
int arr,dep,pref;
};
node a[1000];
sort(a,a+n,comp);

Use can use pair in the stl library of c++ . You can store them as a pair of number and then sort them , sorting will be done on the basis of first number . You can access elements by using variable.first and variable.second .
pair<int,int> a;
cin>>a.first>>a.second;
sort(a,a+n)
