The time conversion of normalized time to the railway is a simple algorithm
|
|
because we know that if the time is in 'AM' value it means they only want
|
|
some changes on hours and minutes and if the time in 'PM' it means the only
|
|
want some changes in hour value.
|
|
|
|
Input Format -> 07:05:45PM
|
|
Output Format -> 19:05:45
