A new architecture, with Nlayers, isproposed. Userapplication at the top layer generates a message of M bytes. At each layer, an Hbytesheader isadded. The lastlayer of that architecture also adds T bytes trailer. In this architecture, the message M is not dividedinto smaller packetsat any layer. What is the size of the finalmessage (in bytes)transferred bythe lower layer?

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:
