.what is the purpose of the code in the "mystery block" or in other words ,what is the value calculated in M2

this is a c code ,run the program.in the code there is a section i added comments to saying beginning of mystery box and end of mystery box.now the code inbetween im trying to understand what the purpose of that code is in the entire program
