// not equal operator
console.log(3 != 2); // true
console.log('hello' != 'Hello'); // true
// strict equal operator
console.log(2 === 2); // true
console.log(2 === '2'); // false
// strict not equal operator
console.log(2 !== '2'); // true
console.log(2 !== 2); // false

} else if (num2 > num1 && num2 > num3) {

}
//Output: num3 is bigger then num1 and num2
