# Vector Sort Hackerrank Solution in C++ | Hackerrank Solution

Vector Sort Hackerrank Solution in C++. You are given N integers. Sort the N integers and print the sorted order. Store the N 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 N where N is the number of integers. The next line contains N integers.

Constraints

1 <= N <= 10^5
1 <= Vi <= 10^9, where Vi is the ith 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
