Depth First Search (DFS) algorithm traverses a graph in a depthward motion and uses a stack to remember to get the next vertex to start a search, when a dead end occurs in any iteration. As in the example given above, DFS algorithm traverses from S to A to D to G to E to B first, then to F and lastly to C.

WebIn basic terms, an algorithm is a set of well-defined steps or rules that you need to follow to obtain a pre-determined result. For instance, when we talk about algorithms in computer programming, we already have our input and we know the expected output. Now, an algorithm would be all the defined steps to follow on the input to get the desired ... Inodes exist in a static form on the disk. The kernel reads them into in-core inodes and modifies them. Disk inodes consists of the following fields: 1. Owner information: ownership is divided into a user and a group of users. Root user has access to all the files. 2. File type: it states whether a file is a normal file, a directory, … See more In UNIX, the data in files is not stored sequentially on disk.
