A method that always produces a problem solution, though not necessarily very efficiently, is known as an algorithm.
What is an Algorithm?An algorithm is a step-by-step procedure for solving a problem or achieving a specific goal. It is a set of instructions that, if followed in the correct order, will always produce the same result.
Algorithms are often used in computer programming and other fields where precise, repeatable steps are necessary to solve a problem or accomplish a task.
Algorithms are typically designed to be efficient and effective, but they may not always be the fastest or most efficient way to solve a problem. Other approaches, such as heuristics, may be faster but less reliable, as they may not always produce a solution.

How do you find the factorial return of a number?Factorial of a positive integer (number) is the sum of multiplication of all the integers smaller than that positive integer. For example, factorial of 5 is 5 * 4 * 3 * 2 * 1 which equals to 120.

what is the running time of bfs if we represent its input graph by an adjacency matrix and modify the algorithm to handle this form of input?
Using adjacency matrix representation will change the time of scanning through neighbours from O(E) to O(V²).
Therefore, total running time becomes O(V² + V), that is, O(V²).
What is adjacency matrix?An adjacency matrix, which is a square matrix used to represent a finite graph, is a tool in graph theory and computer science. If two sets of vertices in the graph are adjacent or not, it is indicated by the matrix's elements.
A (0,1)-matrix with zeros on its diagonal makes up the adjacency matrix in the special case of a finite simple graph. The adjacency matrix is symmetric if the graph is undirected, which means that every edge is directed in only one direction. In spectral graph theory, it is investigated how a graph's adjacency matrix's eigenvalues and eigenvectors relate to one another.
It is important to distinguish a graph's adjacency matrix from its degree matrix and incidence matrix, which both represent matrices differently and contain elements that indicate whether or not vertex-edge pairs are incident.

The solution can be expressed as *(a + 3) in pointer notation is equivalent to a[3] in C.
The addresses of dynamically allocated arrays and arrays supplied as parameters to functions are stored using pointers. We must add 1 to the array's first row in order to access the second element: (Matrix[0] plus 1) The address of the first member of the array's first row is returned by the expression matrix[0]. This address is the location of an integer array. The components in this program are kept in the integer array data[]. The array's components are then accessed using the pointer notation.
