프로그래머스

 

1. Java

class Solution {
    public String solution(String video_len, String pos, String op_start, String op_end, String[] commands) {
        String answer = "";
        String video_start = "00:00";
        String pos_next = pos;
        for ( String com : commands ) {
            if ( op_start.compareTo(pos_next) <= 0 && op_end.compareTo(pos_next) > 0 ) {
                pos_next = op_end;
            }
            String[] p = pos_next.split(":");
            int p_next_mm = Integer.parseInt(p[0]);
            int p_next_ss = Integer.parseInt(p[1]);
            if ( com.equals("prev") ) {
                p_next_ss -= 10;
                if ( p_next_ss < 0 ) {
                    p_next_ss += 60;
                    p_next_mm--;
                }
            } else if ( com.equals("next") ) {
                p_next_ss += 10;
                if ( p_next_ss >= 60 ) {
                    p_next_ss -= 60;
                    p_next_mm++;
                }
            }
            // pos_next = String.format("%02d", p_next_mm)+":"+String.format("%02d", p_next_ss);
            pos_next = (p_next_mm < 10 ? "0"+p_next_mm : p_next_mm) + ":" + (p_next_ss < 10 ? "0"+p_next_ss : p_next_ss);
            if ( op_start.compareTo(pos_next) <= 0 && op_end.compareTo(pos_next) > 0 ) {
                pos_next = op_end;
            } else if ( pos_next.compareTo(video_start) < 0 ) {
                pos_next = video_start;
            } else if (pos_next.compareTo(video_len) > 0  ) {
                pos_next = video_len;
            }
        }
        answer = pos_next;
        return answer;
    }
}

 

2. Python

        p_next_mm = int(p[0])
        p_next_ss = int(p[1])
        if com == "prev" :
            p_next_ss -= 10

        if op_start <= pos_next and op_end > pos_next :
            pos_next = op_end
        elif pos_next < video_start :
