Strings and Anagrams

Alex Chen30 min readUpdated

An anagram problem came up live in a junior Tel Aviv loop, and staff and senior candidates in Israel got a take-home on the same idea, a small web service built around the same key. The key you hash on in the live version becomes the index of that service.

The other two come from timed tests, an online assessment and a Codility task. One is the hardest of the three to spot from its wording, and the other allows no extra data structures. Hidden tests grade both timed problems, so a slow or sloppy answer can fail without you noticing. Check your complexity and your edge cases before you submit.
