Idea about this case [forgive my poor English]

  • 0

    As we know,
    HOUR is from 0 to 11,
    MIN is from 0 to 59.
    So there are 12*59=720 possible situations.
    Why not prebuilt all the possible situations in 10 string[]?
    720 is not a big number.
    And I think use more memory for more efficient code is nice.

    Plz show me if I was wrong.
