# Recess Week Challenge Hackerrank Guide¶

Typically, the first line of the question specifies the parameters for the input, such as the number of lines, values of variables. It is usually followed by a specified number of lines containing data separated by spaces.

Input Example (2 represents the number of lines to be followed by $$(x)$$, 1 8 3 is one line of data (to be read into first line of list), 4 5 6 is the second line of data (to be read into second line of list))

2
1 8 3
4 5 6


Output Example

1 2 3


## Python3 Guide¶

To read the first line of input,

x = int(input()) # The int() is used to convert input from a string to integer


To read the subsequent 2 lines of input

all_lists = []
for j in range(x):
my_list = []
my_list = [int(i) for i in input().split()] # A list of integers
all_lists.append(my_list)


For printing output

print(a, b, c)


## C++ Guide¶

You will require the following libraries

#include <iostream> // To read from input and to print output
#include <array> // To read the tuple
#include <vector> // To read the lines of input


To read the first line of input

int x;
std::cin >> x;


To read the subsequent 2 lines of input

std::vector<int> v(x); // Initialise vector with size x
for (int i = 0; i < x; ++i)
{
std::cin >> a1 >> a2 >> a3;
v.at(i) = std::array<int, 3>{ a1, a2, a3 }; // Assign element at i index of vector to array of inputs
}


To print to output

std::cout << a << b << c;
