You are given a string ‘STR’ containing space-separated words. A word is a sequence of non-space characters. Your task is to reverse the order of words in ‘STR’.

Note: Try to do it in-place without allocating extra space.

Example:

‘STR’ = “when in doubt use brute force”
The reverse order of words in ‘STR’ is: “force brute use doubt in when”.

Note:

1. ‘STR’ does not contain any leading or trailing spaces.
2. The words are always separated by a single whitespace character.

You have been given an array/list 'ARR' of integers. Your task is to find the second largest element present in the 'ARR'.

Note:

a) Duplicate elements may be present.

b) If no such element is present return -1.

Example:

Input: Given a sequence of five numbers 2, 4, 5, 6, 8.

Output:  6

Explanation:
In the given sequence of numbers, number 8 is the largest element, followed by number 6 which is the second-largest element. Hence we return number 6 which is the second-largest element in the sequence.
