This guy cannot speak english well please... if u plan to take 9 am class be ready to skip and watch other sessions lecture cause this guy is unintelligable, homework is super easy but the mid term and exam is conducted leetcode style where every fail attempt deducts your mark which is stupid cause when u fail a test case it doesnt say what u fail so you have to decide whether you decide wheter you get half mark or even less cause 'every attempt' cost. Overall the difficulty is not bad and the required answers are similar in difficulty to leetcode easy and the harder ones are leet code mediums not difficult at all.
