Vector-Sort in C++ : Hacker Rank Solution : Digit Wood

c++
,

You are given n integers. Sort the n 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.

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

SOLUTION :


#include <cmath>
#include <cstdio>
#include <vector>
#include <iostream>
#include <algorithm>
using namespace std;


int main() {
    /* Enter your code here. Read input from STDIN. Print output to STDOUT */   
    
    vector <int> a;
    int n, k;
    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] << " ";
    }
    
    return 0;
}
