+Write a program that asks the user to enter a number of seconds.

+    If the number of seconds entered by the user is greater than or equal to 60,
+    the program should display the number of minutes in that many seconds.
+
+•  There are 3,600 seconds in an hour.
+    If the number of seconds entered by the user is greater than or equal to 3,600,
+    the program should display the number of hours in that many seconds.

+•  There are 86,400 seconds in a day.
+    If the number of seconds entered by the user is greater than or equal to 86,400,
+    the program should display the number of days in that many seconds.
