Set would also be log(n) where n is avg number of timestamps for a key, because inserting a new key into treeMap requires sorting that key ascendingly among existing keys

Hi Eric, a tip of the set method when using the treemap solution:
public void set(String key, String value, int timestamp) {
map.computeIfAbsent(key, k->new TreeMap<Integer, String>()).put(timestamp, value);
}

which solution do you recommend the binary search one or the tree map one
