Write a program to detect if a word or phrase is a palindrome. The program should: 1. prompt the user to enter a word or phrase 2. determine if the word or phrase is a palindrome 3. let the user know if their entry is or isn't a palindrome 4. continue asking the user for a word or phrase to check, until they provide an empty string (just hit at prompt)

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:
