   Vector - Sort
   
   

Objective

You are given  integers.Sort the  integers and print the sorted order.
Store the  integers in a vector.Vectors are sequence containers representing arrays that can change in size.
Declaration:
vector<int>v; (creates an empty vector of integers)

Size:
int size=v.size();
Pushing an integer into a vector:
v.push_back(x);(where x is an integer.The size increases by 1 after this.)
Popping the last element from the vector:
v.pop_back(); (After this the size decreases by 1)
Sorting a vector:
sort(v.begin(),v.end()); (Will sort all the elements in the vector)

Input Format

The first line of the input contains  where  is the number of integers. The next line contains  integers.

Constraints

, where  is the  integer in the vector, where  is the  integer in the vector.

Output Format

Print the integers in the sorted order one by one in a single line followed by a space.

Sample Input

       5

    1 6 10 8 4

Sample Output

    1 4 6 8 10

    cin >> n;

    

    for (int i=0; i<n; i++) {

        cin >> k;

        a.push_back(k);

    }

    

    sort(a.begin(), a.end());

    

    for(int i=0; i<n; i++) {

        cout << a[i] << " ";
