 In process 0, read from file 'data. txt' text. Split this text into parts according to number of processes available.
 Send to each process their part of text.
 Each process should reverse received text and send back to main process.
 Main process (process 0) receives all reversed texts, joins them into one and prints to file
'reversed. txt'.
 Run this program on 1, 2, 8, 16 processes

Use a physical stopwatch to record the length of time it takes to run the program. calculate the difference obtained by calls to the method system.currenttimemillis() just before the start of the algorithm and just after the end of the algorithm. calculate the difference obtained by calls to the method system.currenttimemillis() at the start of the program and at the end of the program so that the elapsed time includes the display of the result. use the value returned by the method system.currenttimemillis() just after the end of the algorithm as the elapsed time.
