In this tutorial, we’ll learn how to find a cycle starting node in a linked list. Also, we’ll analyze the different time and space complexities of each approach. Moreover, we’ll look at the most efficient algorithm and prove it. Furthermore, we’ll prove its linear time complexity....

I used a helper function to return the height of current node. According to the definition, the height of leaf is 0.h(node) = 1 + max(h(node.left), h(node.right)). The height of a node is also the its index in the result list (res). For example, leaves, whose heights are ...

Each directory on a normal Unix filesystem has at least 2 hard links: its name and its `.' entry. Additionally, its subdirectories (if any) each have a `..' entry linked to that directory. When find is examining a directory, after it has statted 2 fewer subdirectories than the ...
