You will be given N number of strings. You have to find the lexicographically smallest string and the lexicographically largest string among these strings.
Example 1:
Input:
N = 3
strings = a , ab , abc
Output: a abc
Explanation: Lexicographically smallest is
"a" and lexicographically largest is
"abc".
 
Example 2:
Input:
N = 2
strings = abc , abc
Output: abc abc
Explanation: Lexicographically smallest is
"abc" and lexicographically largest is
"abc"
 
Your Task:  
You dont need to read input or print anything. Complete the function orderStringÃ¢â¬â¹() which takes a 2d character array and an integer N as input parameter and returns an array of size 2 where first value should be lexicographically smallest string and second value should be lexicographically largest string.
 
Expected Time Complexity: O(N* max of all string length ).
Expected Auxiliary Space: O(1).
 
Constraints:
1 <= N , length of each string <= 10^{3}
