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

AC in one, using dp and deque

Wrong answer on judge 5..Please help

Used segtree and got AC but 0.07s not nice though

Interesting problem... 1st used Brute Force, Then used DP in O(n)!

Try using Deque.
O(n) Deque .02s
O(n*k) sliding Window .02s

ac in one go
simple implementation of sliding window !!

Brute Force worked, i wasnt expecting that because time complexity was O((n-k)*k).Accepted appeared like Magic.

Great application of Deque!
AC in one GO!

When k<= 3 brute force is faster, this optimization speed up my solution at 15%. About NZEC in python. Read input in such way: >>>words = sys.stdin.read().split() >>>n=int(words[0]) >>>k=int(words[-1]) >>>lst=map(int,words[1:n+1])
