For this exerciseuse the following 2D array, which is already declared and Initialized in your programming environment below. Do not rename the provided array - your program should refer to it as a 34 42 38 36 31 47 28 50 40 46 35 20 44 43 40 31 36 39 44 45 26 50 43 37 Your task is to output the sum of all values in the 2D array , along with the average of all values in the 2D array , as seen in the sample run below . Note : Be sure that your program accounts for arrays of any size , not just arrays that are 5 * 5 5. Your program will be tested against arrays of size n by n. It should work for any square array , not just the one shown . You should also use for loops in your program , not while loops .

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:
