    Java (without using LocalTime or any pre built formatter:

    String solution = "";
    String meridian = s.substring(s.length()-2, s.length());
    String pureTime = s.substring(0, s.length()-2);
    String hours = s.substring(0, 2);

    
    if(meridian.equals("AM") && !hours.equals("12") || (meridian.equals("PM") && hours.equals("12"))) {
        solution = pureTime;
    } else if (meridian.equals("AM")) {
        solution = "00" + pureTime.substring(2,pureTime.length());
    } else {
        int new_hours = Integer.parseInt(hours) + 12;
        solution = new_hours + pureTime.substring(2,pureTime.length());
    }
    return solution;

    Java

    LocalTime parsedTime = LocalTime.parse(s, DateTimeFormatter.ofPattern("hh:mm:ssa", Locale.US));
        return parsedTime.format(DateTimeFormatter.ofPattern("HH:mm:ss"));

    Scala-

    ` def timeConversion(s: String): String = { // Write your code here var hour = s.substring(0, 2).toInt val amPm = s.takeRight(2)

        if (amPm == "AM") {
        if (hour == 12) hour = 0
        } else if (amPm == "PM") {
    if (hour != 12) hour += 12
    }
    f"`$hour%02d$`{s.substring(2, 8)}"
}

    DateTime input = DateTime.ParseExact(s, "hh:mm:sstt", System.Globalization.CultureInfo.InvariantCulture); return input.ToString("HH:mm:ss");

    def timeConversion(s):
    from datetime import datetime
    return(datetime.strptime(s, '%I:%M:%S%p').strftime("%H:%M:%S"))
