    Simple solution in C++

    `
string timeConversion(string s) {
    int n = s.size();
    string hourStr = s.substr(0,2);
    int hour = std::stoi( hourStr);
    if (s[n-2]=='P' && hour<12) {
        hour+=12 ;
        hourStr = to_string(hour);
    }
    if (s[n-2]=='A' && hour==12) {
        hourStr = "00";
    }
    s = hourStr.append(s.substr(2,n-4));
    
    return s;

}

    My solution in Java:

    public static String timeConversion(String s) {
    // Write your code here
        String[] time = s.split(":");
        int hour = Integer.valueOf(time[0]) + 12;
        if(time[2].contains("PM")){
            time[0] = String.valueOf(hour==24?hour-12:hour);
        } else {
            time[0] = time[0].contains("12")?"00":time[0];
        }
        return time[0]+":"+time[1]+":"+time[2].substring(0, 2);
    }

    Using C++ Language.....

    string timeConversion(string s) {

    // Extract the period (AM/PM)
string period = s.substr(s.length() - 2);
// Extract the hour, minute, and second
int hour = stoi(s.substr(0, 2));
string minute_second = s.substr(2, 6);

// Convert based on AM/PM period
if (period == "AM") {
    if (hour == 12) {
        return "00" + minute_second; // Midnight case: 12 AM -> 00
    } else {
        return s.substr(0, 8);  // Keep the time as it is, remove AM/PM
    }
} else {  // PM case
    if (hour == 12) {
        return "12" + minute_second;  // Keep the time as it is for 12 PM
    } else {
        return to_string(hour + 12) + minute_second;  // Add 12 to PM times
    }
}

    }

    python without using time module

    def timeConversion(s):
    # Write your code here
    hrs = "12"
    splitted = s.split(":")
    print(splitted)
    if "PM" in splitted[2][2:]:
        if "12" not in splitted[0]:
            hrs = str(int(hrs) + int(splitted[0]))
    if "AM" in splitted[2][2:]:
        if "12" not in splitted[0]:
            hrs = splitted[0]
        else:
            hrs = "00"
    return hrs+":"+splitted[1]+":"+splitted[2][:2]

    Python One Liner using time module:

    import time
def timeConversion(s):
    # Write your code here
    return time.strftime("%H:%M:%S", time.strptime(s, "%I:%M:%S%p"))
