SPOJ Problem Set (classical)

10582. subarrays

Problem code: ARRAYSUB


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

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

I think that the numbers of the array are negative too in the test cases. Gave me several WA's!!!

why my O(3n) soln is taking so much time ;/

I don't know O(n) solution for this problem yet, but my O(n*log n),[using binary search] is 0.03s :-P

Hello Coders !!
I know you all are doing great !!
O(nlog(n)) solution can be easily think for this problem sets/priority queue/ segment tree but there exists a O(n) solution for this problem think for O(n) solution you will surely learn something my last submission is on the same algo . and you dont believe it is the smallest code among all :D
