Campus Test Story Problems

These problems belong to one route: on-campus hiring in India, internships included, where Wells Fargo runs its coding test on SHL or AMCAT. If you applied as a US engineer, a US intern or an experienced hire, your test runs on HackerRank and these stories are unlikely to show up. The warm-up problems and the arrays and strings lesson are a better use of your time.

On the campus route, expect stories. The coding section likes them long. A prompt can run a full page about a company and its systems before it asks anything. Under the story is usually a problem you've already met, and once you spot it the code is short.

Before you type, rewrite the prompt as plain input and output. Read it once for the story and again for the numbers. Then check the limits. Several of these problems allow values up to 10^8, so a direct simulation times out and only the known faster method scores.

When a story leaves a rule loose, like how to round or which item wins a tie, let the sample output settle it. The six problems below start with the ones that come up most, and each one comes with a walkthrough of the faster method and why the limits call for it.
