Given a list of characters, merge all of them into a string.
Example 1:
Input:
N = 13
Char array = g e e k s f o r g e e k s
Output: geeksforgeeks 
Explanation: combined all the characters
to form a single string.
Example 2:
Input:
N = 4
Char array = e e b a
Output: eeba
Explanation: combined all the characters
to form a single string.
Your Task:
You dont need to read input or print anything. Complete the function chartostr() which accepts a char array arr and its size  N  as parameter and returns a string.
