+// You are perhaps tempted to try slices on strings? They're arrays of
+// u8 characters after all, right? Slices on strings work great.
+// There's just one catch: don't forget that Zig string literals are
+// immutable (const) values. So we need to change the type of slice
+// from:
+//
+//     var foo: []u8 = "foobar"[0..3];
+//
+// to:
+//   
+//     var foo: []const u8 = "foobar"[0..3];
+//
+// See if you can fix this Zero Wing-inspired phrase descrambler:
+const std = @import("std");
