Problem Statement

Create and display the sequence of binary digits for a given   non-negative integer. The results can be achieved using built-in radix functions within the language   (if these are available),   or alternatively a user defined function can be used. The output produced should consist just of the binary digits of each number followed by a   newline. There should be no other whitespace, radix or sign markers in the produced output, and leading zeros should not appear in the results.

Let's start with the solution:

    shared void run() {
    
        void printBinary(Integer integer) =>
            print(Integer.format(integer, 2));
    
        printBinary(5);
        printBinary(50);
        printBinary(9k);
    }
