ARRAYSUB  subarrays
Given an array and an integer k, find the maximum for each and every contiguous subarray of size k.
Input
the number n denoting number of elements in the array then after a new line we have the numbers of the array and then k in a new line
n < 10^6
k < 10^5
1 <= k <= n
and each element of the array is between 0 and 10^6
(Edited: In fact, n <= 10^5)
Output
print the output array
Example
Input: 9 1 2 3 1 4 5 2 3 6 3 Output: 3 3 4 5 5 5 6

even brute force got accepted!!

That's weird, I considered a brute force approach and I got AC on my first attempt.

solved it with vectors it took 0.54s

Can the array elements in the input be either space or line separated.(I found some test cases on spoj toolkit where inputted array elements are line separated but here in problem description,array elements in input are space separated .)

why deque is taking so much time ie.. 0.51 seconds...

python 3 bruteforce using max() per each subarray gives TLE, you need to write something better ;)
