"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.

+// Zig 'while' statements create a loop that runs while the
+// condition is true. This runs once (at most):
+//
+//     while (condition) {
+//         condition = false;
+//     }
+//
+// Remember that the condition must be a boolean value and
+// that we can get a boolean value from conditional operators
+// such as:
+//
+//     a == b   means "a equals b"
+//     a < b    means "a is less than b"
+//     a > b    means "a is greater than b"
+//     a != b   means "a does not equal b"
+//
