say hello world with C++ - Solution in Hacker Rank - hackerranksolutions8

  Objective This is a simple challenge to help you practice printing to  stdout . You may also want to complete  Solve Me First  in C++ before attempting this challenge. We’re starting out by printing the most famous computing phrase of all time! In the editor below, use either  printf  or  cout  to print the string  Hello ,World!  to  stdout . The more popular command form is  cout . It has the following basic form: cout<<value_to_print<<value_to_print; Any number of values can be printed using one command as shown. The  printf  command comes from C language. It accepts an optional format specification and a list of variables. Two examples for printing a string are: printf("%s", string);   printf(string); Note that neither method adds a newline. It only prints what you tell it to. Output Format Print   Hello ,World!   to stdout. Sample Output Hello, World! Solution:- //Say Hello, ...

Vector-Sort in C++ – Solution in Hacker Rank - hackerranksolutions8

      

Problem

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 Vertex

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 :

//Vector-Sort in C++ - Hacker Rank Solution
#include <cmath>
#include <cstdio>
#include <vector>
#include <iostream>
#include <algorithm>
using namespace std;


int main() 
{
    /* Vector-Sort in C++ - Hacker Rank Solution Start */
    int n,i;
    cin >> n;
    vector<int> numbers(n, 0);
    for(i = 0; i < n; i++) 
    {
        cin >> numbers[i];
    }

    sort(numbers.begin(), numbers.end());

    for(i = 0; i < n; i++) 
    {
        cout << numbers[i] << " ";
    }
    /* Vector-Sort in C++ - Hacker Rank Solution End */
    return 0;
}
