QUESTION 1 a) What are the advantages of using a collections framework like the Java Collections Framework? b) Give four (4) reasons why it's important to perform algorithm analysis. c) Explain the difference between the Top-down and Bottom-up approaches to algorithm design. d) What are the core operations that every collection ADT should provide? e) Explain the concept of time complexity in the context of data structures. How is it different from space complexity, and why is it important to analyze the time complexity of algorithms and data structures when designing software? [6] QUESTION 2 a) Define a record called Students to store details of each student. b) Declare an array called studentData to store the details of 10 students. c) Develop a method to populate the array. d) Develop a method to search for a student named “John sequentially". e) Code a method to perform a shell sort on the array, sorting data in ascending order of marks achieved in November. The following details of COM2224 students are required: Student Number, Name, Surname, and Marks for Main Exams. QUESTION 3 Study the below algorithm to delete and re-organize elements into an array. algorithm Deletion (arrayA, index) Pre: index is the position of element to be deleted. Post: Display a new re-organized array index_copy index while index_copy is less than array_size array A[index_copy] is equal arrayA[index_copy + 1] index_copy is equal index_copy + 1 end while array_size equals array_size - 1 display a new re-organized array [6] [4] end Deletion [4] [3] [3] [2] [3] [3] [4] a) Explain how the above algorithm works. [5] [5] b) Convert the above algorithm to a Java method. c) Considering how elements can be deleted in an array, and re-organized the elements, give a detailed explaination how you can efficiently insert new values to an array on any given index.
