Build one day's timetable for a company shuttle bus.
The route rules are as follows; keep them as constants in your program.
- The first bus leaves at 06:00.
- Buses may leave up to and including 22:30 (a bus leaving at 22:30 counts). No bus leaves later than 22:30.
- Rush hours are from 07:00 (inclusive) to 09:00 (exclusive) and from 17:00 (inclusive) to 19:00 (exclusive).
If a bus leaves during rush hours, the next bus leaves R minutes later; otherwise N minutes later.
The input gives N and R.
For every hour that has at least one departure, from the earliest hour, print one line with "HH:" followed by that hour's minutes in order, each preceded by a single space (for example "07: 20 35 50").
Write hours and minutes with two digits (6 o'clock is 06, 5 minutes is 05).
Hours with no departure get no line.
On the last line print "total" and the number of departures in the day, separated by one space.
Input
One line with N and R (1 ≤ R ≤ N ≤ 180, integers)
Output
One line "HH: MM MM …" per hour with departures, then "total count"
When you run, these lines are fed to input()/stdin in order (the program doesn't stop to ask).

Constants are spelled differently in each language. Python has no syntax for them, so an uppercase name like FIRST = 360 is only a promise. JS/TS use const, Java static final int, C# const int (arrays and tuples cannot be const, so use static readonly), C #define FIRST (6 * 60) or const int, and C++ constexpr int. Craykon has no constants, so you keep a variable you promise not to change, first = 6 * 60;. JS const and Java final only fix the name, so changing an array slot with RUSH[0][0] = 0 is not stopped (TS readonly or JS Object.freeze stops it). Where you declare variables matters too. The hour being collected and its list of minutes must be created outside the loop, so that the last hour (22) can still be printed after the loop ends. In JS/TS (let/const), Java, C#, C and C++ a variable created inside a {} block is not visible outside it, and in Craykon a variable first assigned inside a block is not visible outside either. Python blocks do not create a scope, so a variable created inside is visible outside. If you do not start a new minute list when the hour changes, the earlier minutes keep piling up, and if you do not print the last hour after the loop, the 22 line goes missing. Joining: Python " ".join(minutes), JS/TS minutes.join(" "), Java String.join(" ", minutes), C# string.Join(" ", minutes), Craykon minutes.Join(" "). C has no join, so print "06:" and then put a space in front of each minute, as in " 00". If the header is already "06: " you get two spaces. The boundaries are traps as well: rush hours exclude their end (start <= t && t < end), so the bus after one leaving at 09:00 comes N minutes later, while a bus leaving at 22:30 is included (t <= LAST). Write hours and minutes with two digits using %02d, padStart(2, "0"), D2, or Craykon PadLeft(2, "0").
