// Algorithm Explained
// -------------------
//
// If we divide the total number of seconds by 60 (the number of seconds in a 
// minute) then the quotient will be the total number of minutes and the 
// remainder will be the number of seconds left over after accounting for the 
// number of minutes.
//
// e.g. 200,000 / 60 = 3,333 remainder 20
//
// If we take that total number of minutes and divide it by 60 (the number of 
// minutes in an hour) then the quotient will be the total number of hours and
// the remainder will be the number of minutes left over after accounting for 
// the number of hours.
//
// e.g. 3,333 / 60 = 55 remainder 33
//
// And if we take that total number of hours and divide it by 24 (the number of
// hours in a day) then the quotient will be the total number of days and the 
// remainder will be the number of hours left over after accounting for the 
// number of days.
//
// e.g. 55 / 24 = 2 remainder 7
//
// So 200,0000 seconds is 2 days, 7 hours, 33 minutes, and 20 seconds

#include <stdio.h>

int main(void)

  // stores the total initial amount of seconds
  int total_seconds = 0;

  // Store the total number of whole minutes and hours as used in the above 
  // calculations
  int total_minutes = 0;
  int total_hours = 0;
  
  // Store the equivalent number of days, hours, minutes and seconds
  int days = 0;
  int hours = 0;

  total_minutes = total_seconds / 60;
  
  // Find the remaining number of minutes (minutes) and total number of hours

  // Find the remaining number of hours (hours) and total days (days)
