Thank you My first time sharing a solution (as well as earning compliments from it)
nice work!
i ended up with something almost identical, though i used defaultdicts with sets
def freqQuery(queries): results = [] lookup = dict() freqs = defaultdict(set) for command, value in queries: freq = lookup.get(value, 0) if command == 1: lookup[value] = freq + 1 freqs[freq].discard(value) freqs[freq + 1].add(value) elif command == 2: lookup[value] = max(0, freq - 1) freqs[freq].discard(value) freqs[freq - 1].add(value) elif command == 3: results.append(1 if freqs[value] else 0) return results
results.append(int(freqs[value] > 0))
