The breadth-first search or BFS algorithm is used to search a tree or graph data structure for a node that meets a set of criteria. It begins at the root of the tree or graph and investigates all nodes at the current depth level before moving on to nodes at the next depth level. You can solve many problems in graph theory via the breadth-first.

The structure is a user-defined data type in C which allows you to combine different data types to store a particular type of record. Structure helps to construct a complex data type in a more meaningful way. It is somewhat similar to an Array. The only difference is that array is used to store a collection of similar datatypes while structure.

YASH PAL January 22, 2021. In this HackerRank Python If - Else problem-solution set, we need to develop a python program that can read an integer value n. and then we need to print the Weird message on the screen if the number is odd. and if n is even and in between 2 to 5 then print Not Weird. and if the n is even and in between 6 to 20 then. A Simple Solution is to consider every petrol pumps as a starting point and see if there is a possible tour. If we find a starting point with a feasible solution, we return that starting point. The worst case time complexity of this solution is O(n^2). An efficient approach is to use a Queue to store the current tour. We first enqueue first.
