int n;
cin>>n;
int a[n];
for(int i=0;i<n;i++)
cin>>a[i];
int i=0,mn;
sort(a,a+n);
mn=a[0];
set <int> s(a,a+n);
for(int aa:s)
cout<<aa;
cout<<endl;
cout<<s.size()<<" size";
when input is
3
1 1 1
why it is not printing size of set???
can any one tell the mistake i have done??
It is printing the size (1) as in this case all elements are the same.
kindly change your ide, it works fine in My ide
its give me output as
1
1 size
A set can’t have copies of same element.
can suggest the good one??
multiset<int> s;
a is not variable it is name of array.
set s(a,a+n); <----- not possible
@gouthamreddy12 , your code is working fine , as you are using set , so it will not have any duplicate items.
For 111, you code is giving 1 as size of your set
