Write a program to display seconds as Minutes and Hours and days

write a program that asks the user to enter a number of seconds. obeying the following conditions:

1. there are 60 seconds in a minute. if the number of seconds entered by the is greater than or equal to 60, the program should display the number of minutes in that many seconds.

2. there are 3600 seconds in an hour. if the number of seconds entered by a user is greater than or equal to 3600, the program should display the number of hours in that many seconds.

3. there are 86400 seconds in a day, if the number of seconds entered by the user is greater than or equal to 86400, the program should display the number of days in that many seconds,
