**"Hello World!" in C**

### Problem Statement :

Objective: In this challenge, we will learn some basic concepts of C that will get you started with the language. You will need to use the same syntax to read input and write output in many C challenges. As you work through these problems, review the code stubs to learn about reading from stdin and writing to stdout. Task: This challenge requires you to print Hello World! on a single line, and then print the already provided input string to stdout. If you are not familiar with C, you may want to read about the printf() command. Example: s="Life is Beautiful" The required output is: Hello, World! Life is beautiful Function Description: Complete the main() function below. The main() function has the following input: string s: a string Prints: *two strings: * "Hello, World!" on one line and the input string on the next line. Input Format There is one line of text, .

### Solution :

` ````
Solution in C :
#include <stdio.h>
#include <string.h>
#include <math.h>
#include <stdlib.h>
int main()
{
char s[100];
scanf("%[^\n]%*c", &s);
printf("Hello, World!\n%s",s);
return 0;
}

Kundu is true tree lover. Tree is a connected graph having N vertices and N-1 edges. Today when he got a tree, he colored each edge with one of either red(r) or black(b) color. He is interested in knowing how many triplets(a,b,c) of vertices are there , such that, there is atleast one edge having red color on all the three paths i.e. from vertex a to b, vertex b to c and vertex c to a .

There is a given list of strings where each string contains only lowercase letters from a - j, inclusive. The set of strings is said to be a GOOD SET if no string is a prefix of another string. In this case, print GOOD SET. Otherwise, print BAD SET on the first line followed by the string being checked. Note If two strings are identical, they are prefixes of each other. Function Descriptio
