Debugging Data Structure Implementation in Dafny
I’m working on a textbook exercise that requires implementing a bounded stack and queue in Dafny with specific behaviors. The stack should behave as a last-in, first-out (LIFO) structure, and the queue as a first-in, first-out (FIFO) structure using two stacks. I have written the code for both classes, but I am facing verification errors that I cannot resolve.
