Given a list of intervals of time, find the set of maximum non-overlapping intervals.\n\nFor example,\n\n    given following intervals:\n    \n    [0600, 0830], [0800, 0900], [0900, 1100], [0900, 1130], \n    [1030, 1400], [1230, 1400]\n    \n    Also it is given that time have to be in the range [0000, 2400].\n    \n    The maximum non-overlapping set of intervals is [0600, 0830], [0900, 1130], [1230, 1400].
