Homework Answers
a) True. Refactoring helps in modification throighout the program
b) For programming languages like C,C++ and all, data type has to be specifically mentioned. For languages like python, they can be interpreted from value so TRUE for python.
c) strings are immutable sequence of characters. Python has four basic inbuilt data structures namely Lists, Dictionary, Tuple and Set. FALSE for python, TRUE for C++
d) The product of procedural abstraction is a procedure. Similarly, the product of data abstraction is an abstract data type (ADT). FALSE
e) TRUE since tack can be implemented using queue module
f) FALSE, FIFI is for queue
g) FALSE, we can use inbuilt classes and methods. We only have to understand how they work, not implementation

Can you please help with the below? 1) Which of the following is true about using a 2-3-4 tree? a. It is designed to minimize node visits while keeping to an O(log n) search performance b. It is designed to self-balance as new values are inserted into the tree c. As soon as a node becomes full, it performs the split routine d. None of the above 2) Which of the following is true about a binary search tree? a. ...

Backtracking is a computing algorithm using stack to “remember” user-generated events when using a program. A user event may be “pressing the Enter key on keyboard” or “clicking a mouse button”. Stack is a data structure with the Last-In-First-Out property (LIFO). If we push the aforesaid user events into a stack, a computer program using that data structure can “rewind” user events by popping them out of stack one at a time. This backtracking feature is available as Edit ->...

In c++ Section 1. Stack ADT – Overview Data Items The data items in a stack are of generic DataType. This means use should use templating and your Node class. Structure The stack data items are linearly ordered from the most recently added (the top) to the least recently added (the bottom). This is a LIFO scheme. Data items are inserted onto (pushed) and removed from (popped) the top of the stack. Operations Constructor. Creates an empty stack. Copy constructor....
