A binary tree is a tree where each node has at most two children, often referred to as the left and right children. classBinaryNode<T>{varvalue:TvarleftChild:BinaryNode?varrightChild:BinaryNode?init(value:T){self.value=value}} you’ll look at three traversal algorithms for binary trees:...
We have avoided using STL algorithms as the main purpose of these problems is to improve your coding skills and using in-built algorithms will do no good. Nevertheless, we have still used the following common algorithms at several places: ...
I bombed in this interview and still have really no idea how to implement this. The first part asks for the 10 most frequent items in a continuously growing sub-sequence of an infinite list. I looked into selection algorithms, but couldn't find any online versions to solve this problem....
Chapter 1 Data Structures and Algorithms 1.1. Unpacking a Sequence into Separate Variables Problem You have an N-element tuple or sequence that you would like to unpack into a collection of N variables. Solution Any sequence (or iterable) can be unpacked into variables using a simple assignment...
In this article we provide an introduction to data structures and algorithms. We consider some basic data structures and deal with implementations of a dictionary and a priority queue. Algorithms for such basic problems as matrix multiplication, binary search, sorting, and selection are given. The ...
