Which of the following statements is false? Group of answer choices When the model changes, the controller updates the view to present the changed data. The model presents the data stored in the view. When a user provides input, the controller modifies the model with the given input. JavaFX applications in which the GUI is implemented as FXML adhere to the Model-View-Controller (MVC) design pattern, which separates an app's data (contained in the model) from the app's GUI (the view) and the app's processing logic (the controller).

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:
