    JS:

    function timeConversion(s) {
    const parts = s.split(':');

     parts[0] = parts[2].slice(-2) === 'PM' ? 12 + parseInt(parts[0]) % 12 : parts[0];
    if (parts[2].slice(-2) === 'AM' && parseInt(parts[0]) === 12 ) parts[0] = "00";
    parts[2] = parts[2].replace(/[a-zA-Z]/g, '');

    return parts.join(':');
}

    function timeConversion(s: string): string {
    const hour = s.substring(0, 2);
    const amPM = s.substring(8, 10);
    
    let result = '';
    if(hour == '12') {
        result += (amPM == 'PM') ? '12' : '00';
    } else {
        result += (amPM == 'PM') ? Number(hour) + 12 : hour; 
    }
    
    result += s.substring(2,8);
    return result;
}

    def timeConversion(s):
    new_hour=(s[:2])
    if s[:2] == '12':
        if s[-2] == 'A':
            new_hour='00'
        elif s[-2] == 'P':
            new_hour='12'
    elif s[-2] == 'P':
        new_hour=int(s[:2])+12
    return str(new_hour)+s[2:-2]

    Here's my humble solution in Java:

    public static String timeConversion(String s) {
    String meridiem = s.substring(8);
    int hours = Integer.parseInt(s.substring(0, 2));
    String colonsMinutesAndSeconds = s.substring(2, 8);

    if (meridiem.equals("AM") && hours == 12) {
        hours = 0;
    } else if (meridiem.equals("PM") && hours != 12) {
        hours += 12;
    }

    return String.format("%02d%s", hours, colonsMinutesAndSeconds);
}

    My short answer…

    def timeConversion(s):
    return f'{int(s[:2]) % 12 + (0 if s[-2:] == "AM" else 12):02}' + s[2:8]
