Identify computer science algorithm exercises

We currently have at least one, maybe several exercises that asks the learner to implement a specific algorithm.

We discussed whether this type of exercise is a good fit for Exercism, in https://github.com/exercism/discussions/issues/124 and concluded that:

> Instead of asking "Write a program that implements erastosthenes sieve." we should ask "Write a program which returns a list of prime numbers, there are a couple of efficient algorithms: erastostenes sive, wheel sieve, etc", perhaps even with links.

We need to identify which exercises target an algorithm rather than targeting _what the algorithm does_.

The one that started the discussion in `sieve`, but I'm not sure if that's the only one.

Once we've identified them, we need to open a new issue to implement the new exercise and deprecate the old one.

## Exercises identified as too specific

- `sieve`
- `binary-search`
