Lena was working on a small utility for the internal dashboard to help the team find specific deployment records within our archived logs. Eva pointed out that these logs often get shifted during the backup process, meaning the sequence doesn't always start from the beginning, and some records might be repeated if a deployment was retried. Eva asked Lena to update the helper so it can still accurately confirm whether a specific record exists in these shifted lists. For example, if the logs are organized as [5, 6, 1, 1, 2, 5] and a developer looks for record 2, the utility should quickly confirm it is present.
