- String reversal is considered one of the applications of Stack data structure. You are required to; Write a java program to reverse a given string using stack ADT. Your program must implement a function named reverseMyId() for string reversal. Call reverseMyId() function in the main() function with your ACTUAL student Id as string and print it in the reverse order. For example, if your ACTUAL student id is s101145366, the program will output it as Show the snapshot of the output screen. Create two tables (as shown below) to display how the string is added to and removed from the stack. [Hint: Number of columns is equal to the number of characters in your string.] For Insertion … … … … … For Deletion … … … … … …Q3: Write the C++ code of Stack which is performed multiple task which are given below and performed all task by using Arrays. Push values 10, 20, 5 , 50, 40, 60, 45 Pop values 45, 60, and 40 Sort all values in Stack Please create is empty and stack function for telling them stack is empty or full.NOTE: PLEASE SOLVE THE QUESTION PROPERLY AND ACCORDING TO THE REUIRED THINGS.This code will be in C++ and will have 3 files. This lab will test your ability to use a custom stack class and a custom queue class. It will also test your ability to use a standard algorithm from STL. ReOrder ReOrder() takes three arguments as shown in Reorder.cpp. Complete this function using stack and queue. The number 0 is used as a delimiter between sets of numbers. The new array should have all negative numbers on one side and all positive numbers on the other side. The zero should be pushed to the end of the array. See the sample run below. Custom Compare Function The custom compare function is used in conjunction with the standard sort function. The numbers to be sorted are of a standard data type but create this custom compare function anyway. The function should result in a sorted array from the greatest number to the least number. Sample Run A sample run is as follows: array: -3 2 -1 5 1 -4 0 11 12 13 -11 -12 0 -1 -2 6 8 7newArray: -3 -1 -4 1 5 2 -11 -12 13 12 11 -1 -2 7 8…
