7.Which of the following is NOT a valid application of a queue data structure?Printer spoolingBreadth-first search (BFS) algorithmCPU schedulingImplementing a back button in a web browser
Solution
The option "Implementing a back button in a web browser" is NOT a valid application of a queue data structure. This is because the back button in a web browser is typically implemented using a stack data structure, not a queue. Stacks follow a Last-In-First-Out (LIFO) principle, which is suitable for the back button functionality, as the most recently visited pages are accessed first. On the other hand, queues follow a First-In-First-Out (FIFO) principle.
