Read from STDIN, Write to STDOUT

Problem

Read different types of data from standard input, process them as shown in output format and print the answer to standard output.

Input format:
First line contains integer N.
Second line contains string S.

Output format:
First line should contain N x 2.
Second line should contain the same string S.

Constraints:
0≤N≤10
1≤|S|≤15 where S length of string S 

Sample Input
5
helloworld
Sample Output
10
helloworld
Time Limit: 1
Memory Limit: 256
Source Limit:




/*
// Sample code to perform I/O:

name = Console.ReadLine(); // Reading input from STDIN
Console.WriteLine("Hi, {0}.", name); // Writing output to STDOUT

// Warning: Printing unwanted or ill-formatted data to output will cause the test cases to fail
*/

// Write your code here

using System;

namespace practice
{
class Program
{
static void Main(string[] args)
{
int a = Convert.ToInt32(Console.ReadLine());
string s = Console.ReadLine();
Console.WriteLine(2 * a);
Console.WriteLine(s);
Console.ReadLine();
}
}
}

Find the Runner-Up Score!

  Given the participants' score sheet for your University Sports Day, you are required to find the runner-up score. You are given     scores. Store them in a list and find the score of the runner-up. Input Format The first line contains  . The second line contains an array     of   integers each separated by a space. Constraints Output Format Print the runner-up score. Sample Input 0 5 2 3 6 6 5 Sample Output 0 5 Explanation 0 Given list is  . The maximum score is  , second maximum is  . Hence, we print   as the runner-up score. ### OPTIMIZED ### from   collections   import   Counter if  __ name__  ==  '__main__' :      n  =  int ( input ())      arr  =  map ( int ,   input () . split ())           lis = list ( Counter ( arr ) . keys ())      lis . sort ()  ...

Print All Substrings

  For a given input string(str), write a function to print all the possible substrings. Substring A substring is a contiguous sequence of characters within a string. Example: "cod" is a substring of "coding". Whereas, "cdng" is not as the characters taken are not contiguous Input Format: The first and only line of input contains a string without any leading and trailing spaces. All the characters in the string would be in lower case. Output Format: Print the total number of substrings possible, where every substring is printed on a single line and hence the total number of output lines will be equal to the total number of substrings. Note: The order in which the substrings are printed, does not matter. Constraints: 0 <= N <= 10^6 Where N is the length of the input string. Time Limit: 1 second Sample Input 1: abc Sample Output 1: a ab abc b bc c  Sample Input 2: co Sample Output 2: c co o #include <iostream> #include <cstring> us...
