Note that the MAIN difference between systems prototyping and throwaway prototyping is: "Systems prototyping works with users to quickly develop a simplified working version of the proposed system; while throwaway prototyping focuses more on exploring design alternatives." (Option D)

The prototyping model is a systems development process in which a prototype is produced, tested, and then tweaked until an acceptable output is obtained from which the entire system or product may be developed.

A design's flaws aren't always visible on paper or a computer screen. By making a prototype, you may actually handle a version of your proposed product and assess which features work and which need to be improved. This is your opportunity to gather more precise needs and market input.

The fill handle was used to pull down from B2 and B3 to row 20, so B7 will be filled with the same value as B2 and B3, resulting in B7 having the same value as B2 and B3.

The values in B2 and B3 are copied and applied to the cells below when the fill handle is dragged down from those cells. This indicates that when row 20 is reached by dragging, every cell between B2 and B3 and B20 will have the same value as B2 and B3. As a result, B7 will have the same value as B2 and B3.

An implementation of an Abstract Data Type (ADT) with a programming language is called a Data Structure.

A data structure is a particular method of arranging and conserving data in a computer so that it may be efficiently accessed and manipulated. Arrays, linked lists, stacks, queues, trees, and graphs are a few examples of typical data structures. An ADT defines the interface or set of operations that can be performed on a data structure, while a data structure implementation provides a specific way of organizing and storing the data to support those operations.

An Abstract Data Type (ADT) is a high-level description of the data and operations that can be performed on that data. It defines the interface or set of operations that can be performed on a data structure, without specifying how those operations are implemented.

The test case parameter that would expose the logic error in this method is coll = [10, 20, 15, 5, 7]. The correct option is A.

A logic fault, as used in computer programming, is a flaw that makes a programme run wrongly but not abnormally.

The main problem with the code above is that the while loop compares the element max with the subsequent element using max.

The next element in the array will be compared when using compareTo(itr.next()), however when assigning the value, max = itr.next(), the subsequent element will be assigned to max rather than the one with which it was compared.

Therefore, max is first set to the value 10 for the input Coll=[10, 20, 15, 5, 7]. Then it will be compared to 20, however the next statement max=itr.next() will incorrectly assign 15 to it.
