(2) Attempt any three from the remaining questions.
(3) Assume data if required.
(4) Figures to the right indicate full marks.
1(a) Compare Iteration and Recursion(5 marks) 1(b) Explain different types of data structures with example(5 marks) 1(c) Write a program in Java to implement Binary search on sorted set of integers(10 marks) 2(a) Write a program to implement COPY command for copying bytes from one file to another file using file I/O commands. Program should make use of command line argument.(10 marks) 2(b) Write a program in Java to sort given n integer numbers using heap sort(10 marks) 3(a) Write an ADT for rational numbers addition and multiplication.
