Average of 3 long integers
...nsigned average, subtract it after taking the result, and use an unchecked cast back to Int64 to get a signed average.
To compute the unsigned average, compute the sum of the top 32 bits of the three values. Then compute the sum of the bottom 32 bits of the three values, plus the sum from above, p...

Now we have lots of casting, passing arguments to (recursive) main that are completely ignored (but evaluation to get the increment and decrement are utterly crucial), and of course that completely arbitrary looking number to cover up the fact t...
Initialize a byte array to a certain value, other than the default null? [duplicate]
...
It is also required to cast the element to repeat to byte to get a Byte array, rather than an Int32 array as it would come out in this case. Aka byte[] arr1 = Enumerable.Repeat((byte)0x20, 100).ToArray();
