//TASK
//Clock shows h hours, m minutes and s seconds after midnight.
// Your task is to write a function which returns the time since midnight in milliseconds.

//PSEUDOCODE
// get input time
// convert input time into milliseconds
// hours milliseconds + minutes to milliseconds + seconds to milliseconds
// subtract input time from 0, representing midnight
// convert to positive number since the number would be negative
// return answer

//SOLUTION
// let ans

//TASK
// We need a function that can transform a number (integer) into a string.

// Examples (input --> output):
// 123  --> "123"
// 999  --> "999"
// -100 --> "-100"

//PSEUDOCODE
// receive inputted number from function
// use to.String method on input to create string
// return string
// console.log function (which will give the value because of the return)

//SOLUTION

//TASK
//After a hard quarter in the office you decide to get some rest on a vacation. So you will book a flight for you and your girlfriend and try to leave all the mess behind you.

// Every day you rent the car costs $40. If you rent the car for 7 or more days, you get $50 off your total. Alternatively, if you rent the car for 3 or more days, you get $20 off your total.
