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

Got accepted using SQRT Decomposition!

python users segment tree tle ,use deque or dp .. i optimised to core for segment tree still tle

even brute force got accepted!!

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

Way of solving !!
1.dque - 0.03
2.BF - 0.02
3.priority Q - 0.02
4.segment tree - 0.02
5.Use Self-Balancing BST O(nlogK)

Solved with C++ using:
1-) Brute force: 0.55s
2-) Segment Tree: 0.02s

Conclusion: This would be a much better problem if tests where tighter and Brute force did not get AC

solved it with vectors it took 0.54s

using priority_queue, 0.02 sec
+ fast io, 0.01 sec

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...
can anyone pls check - <snip>
