Suppose you must design a program to calculate the roll-out (number of inches travelled in one revolution of the pedals of a bicycle based on its gear combinations). The user will provide the gear sizes, which must be converted into roll-out for all different gear combinations. How can the flow of user interaction for this problem be designed?
A)Hand-tracing can confirm code that implements gear selection.
B)Pseudocode can guide algorithm design through divide-and-conquer strategy.
C)A storyboard can be used.
D)The physical gears can lead to ideas for the correct algorithm to use.

A storyboard can visually represent the flow of user interaction and help plan the different steps and screens required for the program. It can ensure that all necessary information is collected from the user and that the output is clear and easy to understand. Hand-tracing and physical gears may be useful for testing and implementing the program, but they do not guide the initial design process. Pseudocode can be helpful, but it may not be necessary for a program of this size and complexity.
