4. Write a program that asks the user to enter the number of seconds as an integer value and then displays the equivalent time in days, hours, minutes, and seconds. If the user does not enter an integer value, it asks the user to enter the input again. A way to check to see if a number is an integer is to look to see if x=round(x) where x is your input value. Two other useful function are the rem(x,y) function which gives the remainder when x is divided by y and the floor function which gives the floor of a number (number rounded towards ). The output for part (a) should look like: days = 365 hours = 17 minutes = 46 seconds = 40 Run the program for the following inputs. (a) 31600000 seconds (b) 90061 seconds (c) 36000000 seconds (they say it requires 10,000 hours to become an expert in something) (d) 3610 seconds
