    Python 3 sol:

    def timeConversion(s):
    if s.endswith('PM') and s[:2] != '12':
        s = str(int(s[:2]) + 12) + s[2:]
    elif s.endswith('AM') and s[:2] == '12':
        s = '00' + s[2:]
    return s.strip('PMA')

    My solution in javascript

    function timeConversion(s) { const meridiem = s.slice(-2); let [hour, min, sec] = s.slice(0,-2).split(":"); if(meridiem === "AM" && parseInt(hour) === 12) hour = "00"; if(meridiem === "PM" && parseInt(hour) !== 12 ) hour = parseInt(hour) + 12; return [hour, min, sec].join(":"); }

    def timeConversion(s):
    # Write your code here
    hour = int(s[0]+s[1])
    if s[8:] == "AM":
        if hour == 12:
            hour = 0
    elif s[8:] == "PM":
        if hour != 12:
            hour += 12
            
    return f"{hour:02d}{s[2:8]}"

    My solution for C#.Net. It works for all testcases.

    public static string timeConversion(string s)
    {
        DateTime dt;
        string result = "";
        string meridian = s.Substring(8,2);
        if(DateTime.TryParse(s.Substring(0,8), out dt))
        {
            if(dt.Hour == 12 && meridian == "AM")
            {
                result = dt.AddHours(-12).ToString();
            }
            else if(dt.Hour != 12 && meridian == "PM")
            {
                result = dt.AddHours(12).ToString();
            }
            else
            {
                result = dt.ToString();
            }
        }
        return result.Substring(11,8);
    }
