- 2 DO NOT COPY FROM OTHER WEBSITES Correct and detailed answer will be Upvoted else downvoted. Thank you!Look at this stack frame: Fill in the data types for the following procedure: SomeSub PROC, LOCAL val1: , LOCAL val2: , LOCAL val3: , LOCAL val4:suf: C nn.instru @ 2 S if the stack contains (from top) "5", "4", "3", "2", "1" and element = "new", the stack will contain "5", "4", "3", "new", "new" after interchange (). if the stack contains (from top) "5" and element "new", the stack will contain "new", "new" after interchange(). 30% Write public instanc method for MyStáck, called interchange (T element) to replac the bottom *two* items in the stack with element. wer than two items on the stack, upon return the stack should contain exactly two items that are element. Examples: F2 # ۲ 3 ۳ WE E ص X Assume class MyStack implements the following StackGen interface. For this question, make no assumptions about the implementation of MyStack except that the follo wing interface methods are implemented and work as documented. public interface StackGen { void push(T 0); // conventional stack behavior T pop(); // conventional stack behavior T top(); // returns, but does not remove, top element in stack boolean isEmpty(); // returns true…
- 54. What is the difference between the top and pop operations of a stack? Group of answer choices The top operation removes the top item of the stack. The pop operation returns a reference to the top item on the stack and remove it. The top operation removes the top item of the stack. The pop operation returns a reference to the top item on the stack without removing it. The pop operation removes the top item of the stack. The top operation returns a reference to the top item on the stack without removing it. The pop and top operations are doing the same thing which removes the top item of the stack. The pop operation removes the top item of the stack. The top operation returns a reference to the top item on the stack and remove it.Suppose that you have the following declaration:stackType<double> stack(50);double num;and the input is25 64 -3 6.25 36 -4.5 86 14 -12 9Write a C++ code that processes this input as follows: If the number is nonnegative, it pushes the square root of the number onto the stack; otherwise it pushes the square of the number onto the stack. After processing these numbers write a C++ code that outputs the elements of the stack.We have an array. we like to use stack library(Assume it alreay exist and you can use it) to reverse the order of it. Write a method called myRevArray(int[] arr) that would inverse the order of the array with the use of stack you may use the stack library exits and use push and pop from it do not create a new array as it would be memory wasting try to have your code in O(n) where n is the size of array [HINT: O(2n) is till O(n)] The method has no return but we use pass by reference to change arr value (you do not need to do anything but by changing the order of arr it automatically will be reverse
- Consider the following context-free grammar for statements: 1) E > E+T 2) E →T 3) T > I*F 4) T →F 5) F → (E) 6) F → id which can be analyzed with the LR Parsing Table given as following.

Give me the correct interpreter code that compiles for OCaml. The name of the file must be interpreter.ml. Make sure that the code compiles correctly and provide the code with the screenshot of the output.5. fast please Convert the following infix expression into its prefix and postfix equivalents: a / b - (c + d * e) / f * g For any postfix, show the final transformed expression using the stack method for transformation as explained in class showing all the relevant steps. For the prefix, show any needed reversion and the final transformed expression using the stack method for transformation as explained in class showing all the relevant steps. Draw and sequence your diagrams clearly
