Giving a windows size K and an array of size N, find the minimum of each window as it slides through the array.
* You have a data structure of integers, which can be negative, zero, or positive, and you need to support an API with two public methods, insert(int) and getmedian(). Describe a data structure you would use to support this API and describe the running time of the two methods. * Imagine you're writing a function that takes an array of integers and an integer and it needs to return true if any pair in the array sum to the 2nd argument. The array can have negative numbers, zero, or positive numbers. Describe how you would design this function and what its running time would be. I ran through the trivial n^2 solution, then modified it to an nlogn and finally to a linear solution.
