Create a program that does the following:
a) take the string "hey everybody! " and print it out in reversed order.
b) take the string "good morning! " and print it out in all upper case letters.
c) take the string "united states" and print it as united states
d) take the string "bob m walter" and print it out as walter, bob m.
e) take the string "a long way to go" and encode it with a displacement of 4 to encrypt the string. this means your a becomes e. add four to each characters ascii code.

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:
