Chance of 12hr to 24hr

Question

Hello :) i have to chance a 12hr to 24hr ,for example

1:00PM to 13:00

This is my code:

string a = Console.ReadLine();
string[] b1 = {"12","13","14","15","16","17","18","19","20","21","22","23"};
string[] b2 = {"12","1","2","3","4","5","6","7","8","9","10","11"};
string[] c = {"",":",""};
string d = "";

c[0] = a.Substring(0,a.IndexOf(":"));
a = a.Replace(c[0] + ":","");

if (a.Contains("PM")){
for(int i = 0; i < b2.Length; i++){
if(c[0] == b2[i]){
c[0] = b1[i];
break;
}
}
}

a = a.Replace("PM","");
a = a.Replace("AM","");
c[2] = a;

d = c[0] + c[1] + c[2];
Console.WriteLine(d);

but i have a little problem

When i m in the “practice your program “ i fail 2/5 of the case ...

Can you help me?

It is better to save code and share link...

But it seems that your program shloud output 00:00 AM for input 12:00 AM and for single digit input of hour like 1:00 AM, you should output 01:00
