Odd test case: ['wrtkj', 'wrt'] and ['wrt','wrtkj']

  • 0

    In the test case the expected output of
    ['wrtkj', 'wrt'] is ""but for ['wrt', 'wrtkj'] the output is "jkrtw"
    I can understand the logic of the first test case but the second seems quiet misleading, how does it come to the result?
