Also, your *binary_search_right()* is incorrect, it fails when *left = 10**9 - 1* and *func(10**9)* is *HIT* In this case, it returns *10**9 - 1* instead of *10**9*
Wrong implementation: *def binary_search_right(self, left, func):* * right = 10**9* * while left < right:* * m = (left + right) // 2* * f = func(m)* * if f == 'HIT':* * left = m + 1* * elif f == 'MISS':* * right = m* * else:* * return None* * return right - 1* Correct implementation: *def binary_search_right(self, left, func):* * right = 10**9* * while left < right:* * m = (left + right + 1) // 2* * f = func(m)* * if f == 'HIT':* * left = m* * elif f == 'MISS':* * right = m - 1* * else:* * return None* * return right* -- You received this message because you are subscribed to the Google Groups "Google Code Jam" group.
