    //    The main method initializes variable x to 1.
    //    The test('1') call is executed, incrementing the counter zaehler and printing "1\n\r".
    //    Then the test('2') call is executed, incrementing the counter zaehler and printing "2\n\r".
    //    If the condition (x <= 2) is true, the loop continues:
    //
    //    Increment the value of x by 1.
    //    Execute the test('4') call, incrementing the counter zaehler and printing "4\n\r".
    //    Execute the test('3') call, incrementing the counter zaehler and printing "3\n\r".
    //
    //After the execution of test('3'), the loop starts again from step 3 (executing test('2') call). The loop continues to iterate as long as the condition (x <= 2) remains true. When the condition becomes false, the loop breaks.
    //
    //After the loop exits, the program prints the value of zaehler with the message "Zähler = " followed by the counter value.
    //
    //Here's a summary of the code's execution:
    //
    //    Initialize x to 1.
    //    Execute test('1') and increment the counter.
    //    Enter the loop:
    //    a. Execute test('2') and increment the counter.
    //    b. If the condition (x <= 2) is false, break the loop.
    //    c. Increment x.
    //    d. Execute test('4') and increment the counter.
    //    e. Execute test('3') and increment the counter.
    //    f. Repeat steps a-e until the condition (x <= 2) becomes false.
