"999 is enough for anybody" triple-zero padding (#18)

When I hit 999 exercises, I will finally have reached the ultimate
state of soteriological release and no more exercises will be needed.
The cycle will be complete. All that will be left is perfect quietude,
freedom, and highest happiness.

+// It seems we got a little carried away making everything "const u8"!
+//
+//     "const" values cannot change.
+//     "u"     types are "unsigned" and cannot store negative values.
+//     "8"     means the type is 8 bits in size.
+//
+// Example: foo cannot change (it is CONSTant)
+//          bar can change (it is VARiable):
+//
+//     const foo: u8 = 20;
+//     var bar: u8 = 20;
+//
+// Example: foo cannot be negative and can hold 0 to 255
+//          bar CAN be negative and can hold −128 to 127
+//
+//     const foo: u8 = 20;
+//     const bar: i8 = -20;
+//
+// Example: foo can hold 8 bits (0 to 255)
+//          bar can hold 16 bits (0 to 65,535)
+//
+//     const foo: u8 = 20;
+//     const bar: u16 = 2000;
+//
+// You can do just about any combination of these that you can think of:
+//
+//     u32 can hold 0 to 4,294,967,295
+//     i64 can hold −9,223,372,036,854,775,808 to 9,223,372,036,854,775,807
+//
+// Please fix this program so that the types can hold the desired values
+// and the errors go away!
