Algorithms and Me: Heaps : Sliding Window Problem



This problem regularly features in Amazon technical interviews. Basic concept is very simple, but some more variables thrown into question, that makes it more interesting. Problem statement Given a larger integer buffer/array (say size, x), now given a window size (say, n) and a number (say, k). Windows starts from the 1st element and keeps shifting right by one element. The objective is to find the minimum k numbers present in each window. Analysis Given an array of integers, how do we find K smallest or largest elements?  There are a few ways to do so. Method 1 :
