It is often the case that the frictional force on an object will increase as the object moves faster. A fortunate example of this is the parachutist; the role of the parachute is to produce a frictional force due to air drag, which is larger than would normally be the case without the parachute. Consider a very simple example in which the frictional force depends on the velocity. Assume the object velocity obeys an equation of the form $$\frac{dv}{dt}= a - bv $$ where a and b are constants. Think of as coming from a force applied such a gravity and b from friction or drag $(b > 0)$. Solve this equation exactly and using the euler method and compare both solutions. A possible choice: $a=10$, $b=1$

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:
