Visiting a node to put its child nodes in a FIFO queue is a standard approach because you can also implement a queue as a linked list. However, it’s possible to print the current level of the binary tree using a function in C++. ...
infrared, or cameras to detect obstacles and map the surroundings. The robot then employs various algorithms like Depth First Search (DFS), Breadth First Search (BFS), or Wall-Following to map the maze and choose the optimal path. It typically...
The sleep () function causes the program or the process in which it is called, to suspend its execution temporarily for a period of time in seconds specified by the function parameter. Execution is suspended until the requested time is elapsed or a signal or an interrupt is delivered to the...

Cacti have a simpler structure than general graphs, as such it is easier to solve problems on them than on general graphs. But only on paper: cacti and cactus algorithms can be very annoying to implement if you don't think about what you are doing. In the DFS tree of a cactus, for ...
Key concepts to explore: Types of Graphs:Varying types based on connectivity or weights of nodes. Introduction to BFS and DFS:Algorithms for traversing through a graph. Cycles in a Graph:Series of connections leading to a loop. Topological Sorting in the Graph ...
Read how to implement an LRU cache, and then actually write one that gets and sets in worst-case O(1) time. This is a weirdly common interview problem. Learn what happens when you type a URL into your browser and press enter. Be comfortable talking about DNS lookups, the request-respon...
