Anagrams and String Checks

Chewy asks a lot of small string questions. On one HackerRank screen, an anagram question came in two parts, and the second built on the code the candidate had just written. Another string check came up in a final panel, and a new-grad loop used a string problem for live coding.

Letter counts settle the anagram problems. The other two need two indexes or a running total, and nothing from the standard library that would do the work for you.

None of these is hard on its own, but hidden tests check edge cases the prompt doesn't mention, like an empty string or a range that starts at index 0. Say them out loud before you type.
