const movieLength = 8784; // length of movie in seconds
const remainingSeconds = movieLength % 60;
const totalMinutes = (movieLength - remainingSeconds) / 60;
const remainingMinutes = totalMinutes % 60;
const totalHours = (totalMinutes - remainingMinutes) / 60;
const result = `${totalHours}:${remainingMinutes}:${remainingSeconds}`;
console.log(result);
// For the piece of code above, read the code and then answer the following questions
// a) How many variable declarations are there in this program?
// b) How many function calls are there?
// c) Using documentation, explain what the expression movieLength % 60 represents
// https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Arithmetic_Operators
// d) Interpret line 4, what does the expression assigned to totalMinutes mean?
// e) What do you think the variable result represents? Can you think of a better name for this variable?
// f) Try experimenting with different values of movieLength. Will this code work for all values of movieLength? Explain your answer
