2. The requirements engineering process aims to produce as outputs, the system requirement specification, agreed by stakeholders supported by various system models. Consider an example application domain and complete the following tasks: (Points 5) a) Discuss the general inputs, techniques and tools of the requirements engineering process that would be applied to elicit and model the requirements of stakeholders.
b) Identify the weaknesses of most requirements engineering practice, and briefly discuss whether an ideal process can exist for the application domain selected.

Write a program that performs a simple n-body simulation, called "jumping leprechauns." this simulation involves n leprechauns, numberd 1 to n. it maintains a gold value g_i for each leprechaun i, which begins with each leprechaun starting out with a million dollars worth of gold, that is, g_i = 1000000 for each i = 1,. in addition, the simulation also maintains, for each leprachaun,i, a place on the horizon, which is represented as a double-precision floating point number, x_i. in each iteration of the simulation, the simulation processes the leprachauns in order. processing a leprachaun i during its iteration begins by computing a new place on the horizon for i, which is determined by the assignment:
