It is already well-known that using unordered series in Codeforces is super dangerous, and it is not recommended to use them at all unless you know how to prevent them properly (well, even if you know, just using a regular map or set is more beneficial in most cases). Thanks to ...

For the first time I have seen unordered map with this custom hash is getting TLE because of it. (Custom hash fromblog) structcustom_hash{staticuint64_tsplitmix64(uint64_tx){x+=0x9e3779b97f4a7c15;x=(x^(x>>30))*0xbf58476d1ce4e5b9;x=(x^(x>>27))*0x94d049bb133111eb;return...
*** unordered map has a lot of diagnostic tools -- load factor, number of buckets, count in buckets, and whatever else. You can tell if the container is messing up, but its a moving target. It doesn't go from good to bad instantly, it happens over time. It also has tools to fix...

Unfortunately, there is no serial counterpart method for find() similar to concurrent_hash_map::equal_range(). BTW, I would add serial interfaces for all the concurrent containers but our architect is against it. He doubts it has more advantages than potential problems. As for the load factor...
