Write a function that returns the largest value in a stack (only use push and pop)

Expert Solution

Function for above problem

int largest_value_in_stack(stack):
   temp=Stack()       // declare a temporary stack
   max_value=-1       // initialise max value with -1
   while(!stack.isEmpty()):   // iterate till stack becomes empty
       value=stack.pop()       // pop a value from stack
       if(max_value<value):   // update max_value if required
           max_value=value
       temp.push(value)       // add value into temporary stack

   while(!temp.isEmpty()):       // add all the values of temporary stack into origial stack
       value=temp.pop()
       stack.push(value)

   return max_value           // return max_value

JAVA Stack - Implementation. You will be able to use the push, pop and peek of Stack concept. Post-Fix calculator - When an arithmetic expression is presented in the postfix form, you can use a stack to evaluate the expression to get the final value. For example: the expression 3 + 5 * 9 (which is in the usual infix form) can be written as 3 5 9 * + in the postfix. More interestingly, post form removes all parentheses...

Consider an ADT with the same operators as a stack (push(), pop(), size(), empty()), except that the pop() operator returns the largest element rather than the element most recently pushed. For this to make sense, the objects on the stack must be totally ordered (e.g. numbers). Describe array and linked list implementations of the ADT. Your implementations should be as time and space efficient as you can manage. Give the running times for the CRUD operators.

5 marks] A MinStack supports three main operations: the standard Stack operations push(x) and pop() and the non-standard min() operation which returns the minimum value stored on the stack. The zip file gives an implementation SlowMinStack that implements these operations so that push(x) and pop() each run in O(1) time, but min()runs in Θ(n) time. For this question, you should complete the implementation of FastMinStack that implements all three operations in O(1) time per operation. As part of your implementation, you...
