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

You can solve it using monotonic queue in O(n).

n <= 10^5 did not work for me. My solution only got accepted when I used n < 10^6

do anyone have an approach without using set, multiset, i mean not using advantages of ds like multiset..?

Simple solution using policy based ds in c++ :)

Really interesting problem. Learned tons from it. Solved it using c++ map. Because its implemented as a red black tree, we have O(logn) inserts, lookups and deletes.

AC in one go (used Max heap)
