- If the elements “A”, “B”, “C” and “D” are placed in a stack and are removed one at a time, in what order will they be removed?Establish a library. Along with GETMAX, MAXSTACK provides PUSH, POP, and EMPTYSTACK ADT procedures and functions like a typical linked stack. The biggest element in the stack is recorded by the GETMAX function. Can the collection be built with GETMAX requiring only O(1) time complexity?Write the full c code for inserting the node in the singly linked list. Write the full c code for performing the following operation on a stack of size 5. Push(1); Pop(); Push(2); Push(3); Push(4); Pop(); Pop(); Push(5)
- TRUE or FALSE? Answer the following question and state the reason why: A circular linked list has 2 node pointers. cout<<list.back()<<endl; = The back member function returns a reference to the last element in the list. In a Dynamic Stack, the pointer top stays at the head after a push operation. During a Pop operation in Static Stack, the elements are being moved one step up. In a dynamic implementation of stack, the pointer top has an initial value of null.Write a procedure to reverse a linked stack implemented as a doubly linked list,with the original top and bottom positions of the stack reversed as bottom and top,respectively.TRUE or FALSE? Answer the following question and state the reason why: cout<<list.back()<<endl; = The back member function returns a reference to the last element in the list. In a Dynamic Stack, the pointer top stays at the head after a push operation. During a Pop operation in Static Stack, the elements are being moved one step up. In a dynamic implementation of stack, the pointer top has an initial value of null.
- Task:implement a function that reverses a list of elements by pushing them onto a stack in one order and writing them back to the list in reversed order P.S:Answer must be in pythonThe PostfixEvaluator class uses the java.util.Stack class to create thestack attribute. The java.util.Stack class is one of two stack implementationsprovided by the Java Collections API. We revisit the other implementation, theDeque interface, in Chapter 13.The evaluate method performs the evaluation algorithm described earlier, supported by the isOperator and evalSingleOp methods. Note that in the evaluatemethod, only operands are pushed onto the stack. Operators are used as they areencountered and are never put on the stack. This is consistent with the evaluation algorithm we discussed. An operand is put on the stack as an Integer object, insteadof as an int primitive value, because the stack collection is designed to store objects.When an operator is encountered, the two most recent operands are poppedoff the stack. As mentioned above, the first operand popped is actually the secondoperand in the expression and that the second operand popped is the first operandin the expression.…write a function that takes a pointer to the top of a stack <double> and creates and returns a new stack double where the new stack contains all nodes from the original stack with data == 0 c++
- A CapnStackSparrow is an extended stack that supports four main operations: the standard Stack operations push(x) and pop() and the following non-standard operations:• max(): returns the maximum value stored on the Stack.• ksum(k): returns the sum of the top k elements on the Stack.The zip file gives an implementation SlowSparrow that implements these operations so that push(x) and pop() each run in ?(1) time, but max() and ksum(k) run in ?(?) time. For this question, you should complete the implementation of FastSparrow that implements all four operations in ?(1) (amortized) time per operation. As part of your implementation, you may use any of the classes in the Java Collections Framework and you may use any of the source code provided with the Java version of the textbook. Don't forget to also implement the size() and iterator() methods. Think carefully about your solution before you start coding. Here are two hints:1. don't use any kind of SortedSet or SortedMap, these all require…Implement a function void reverseQueue(QueueSLL&) that reverses the elements of a parameter queue. The function uses a stack for the reverse.Short answer: Answer the following in your own words: 1) Your friend says they implemented a stack as a linked list with reference pointers to both a head and the tail node (i.e. they implemented a stack as a double endedlinked list). They said this significantly improved the performance for all functions (push, pop, search, and update). Are they correct? Why or why not?
