Please do the following in Java and make sure that the code is running properly. Do not use other codes from other people because they do not work. It should use stack methods such as pop, push, top, size, isEmpty. Please write the algorithm and complexity too.

Practical application 2: Context-free language recognizer. (a) Design an algorithm that recognizes (accepts) strings of the following context-free language: L={0n1n : where n1}. That is, strings that contain a number of zeros followed by the same number of ones. Examples of strings in the language are: 01, 0011, 000111, etc. Strings that are not in the language are, for example, 10, 00, 111, 1100, 0101, and many more. The algorithm should take a string of 0's and 1's as input and output "Yes" if the string belongs to the language, and "No" if the string doesn't belong to the language. The algorithm should use a stack. When it reads a 0 from the string, it pushes 0 onto the stack. When it reads a 1 , it checks if the stack has a 0 , in which case that 0 is popped from the stack. When the stack is empty and the end of the string is reached, the string is recognized as correct (Yes). Otherwise, the string is not in the language (No). (b) Implement the algorithm of (a) in your favorite programming language and run it on different strings as follows: 01, 000111, 00000001111111, and 10,00,00111, 0101, and others. (c) Consider an input string of size n : (i) what is the worst-case time that your algorithm takes to decide whether or not the string belongs to the language? (ii) Why? Give your answers in terms of the O-notation. (d) [** Optional] Run your algorithm on strings of lengths n=2,4,8,16,32,,220. Compute the running time in nanoseconds and draw a table with the results. Draw a table or a plot of the results for different values of n and compare the results obtained with the complexity you found in (c). Note: if all (or most of) the running times become 0, try running the program 1,000 times and compute the average
