// 1. Write a program that checks if a given number, `num`, is positive, negative, or zero.
/*
var num = 0
var positive = num > 0
var negative = num < 0
if (positive) {
  console.log('positive')
} else if (negative) {
  console.log('negative')
} else {
  console.log('zero')

// 2. Write a program that checks if a given number, `num`, is even or odd.
var num = 5
var remainder = num % 2
var even = remainder === 0

// 3. Write a program that determines if a given year, `year`, is a leap year and
// has 366 days, or a common year and has 365 days.
/*
We use an if statement to check if the year is a leap year based on the following conditions:
  - If the year is divisible by 4 (year % 4 === 0).
  - But not divisible by 100 (year % 100 !== 0).
  - Or it is divisible by 400 (year % 400 === 0).
If any of these conditions are true, the year is considered a leap year and has 366 days. Otherwise, it is a common year and has 365 days.
