Solution: Hash Table
def mostVisitedPattern(username: List[str], timestamp: List[int], website: List[str]) -> List[str]:
patterns = Counter()
user_pattern = defaultdict(list)
for user, _, site in sorted(zip(username, timestamp, website)):
user_pattern[user].append(site)
for user, sites in user_pattern.items():
patterns.update(set(combinations(sites, 3)))
return max(sorted(patterns), key=patterns.get)Time Complexity: , Space Complexity:
