Software Engineer

You are given an array ‘Arr’ consisting of ‘N’ distinct integers and a positive integer ‘K’. Find out Kth smallest and Kth largest element of the array. It is guaranteed that K is not greater than the size of the array.

Example:

Let ‘N’ = 4,  ‘Arr’ be [1, 2, 5, 4] and ‘K’ = 3.  
then the elements of this array in ascending order is [1, 2, 4, 5].  Clearly, the 3rd smallest and largest element of this array is 4 and 2 respectively.

You are given a string (STR) of length N, consisting of only the lower case English alphabet.

Your task is to remove all the duplicate occurrences of characters in the string.

For Example:

If the given string is:
abcadeecfb

Then after deleting all duplicate occurrences, the string looks like this:
abcdef

You're given an alphabetical string ‘S’.

Determine whether it is palindrome or not. A palindrome is a string that is equal to itself upon reversing it.

For example:

‘S’ = racecar
The reverse of ‘S’ is: racecar
Since ‘S’ is equal to its reverse. So ‘S’ is a palindrome.
Hence output will be 1.
