Once I've seen a problem where you are given a dynamic tree and you have to answer 6 or so type of queries (some path and subtree queries). Does anybody know where to find this problem?

sorry can't read ching chong
Ching chong and ching chang chong are pejorative terms sometimes employed by speakers of English to mock or play on the Chinese language, people of Chinese ancestry, or other East Asians or Southeast Asians perceived to be Chinese. Several public commentators have characterized the term as derogatory, noting that assaults or physical intimidation of East Asians are often accompanied by racial slurs or imitation Chinese.
