expected tosses to find 4 heads in a row? expected tosses for THHH ? which of these will take lesser tosses? If you sample in a random series, then, there’s equal probability of finding THHH and HHHH but THHH takes lesser time to come, how do you explain this discrepancy?
How would you evaluate the algorithm?
The first and third ones are coding. The first is pretty easy. The third one I think is a leetcode medium to hard level. The second is a behavioral question.
