Store sequence number

Jharol Rivera

Sep 30, 2023

in the designing of the URL shortening (TinyURL), I don’t understand this

“We don’t need to store this sequence number in the databases”

if we don’t need to do it, how will we know which is the next sequence number to use when computing the hash ?
