+// 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"
+//

+    // Please use a condition that is true UNTIL "n" reaches 1024:
+    while (???) {
+        // Print the current number
+        std.debug.print("{} ", .{n});
+
+        // Set n to n multiplied by 2
