List of Crystal Kata to Update

NOTE: Simply remove the kata from the list after updating.

Crystal 1.0 was added, but the following are not compatible. Please help updating them.

---

Common fixes:

• Replace / with // (floored division)

---

Many of the translations by one user have nested it, and apparently have been displaying a corrupted output for many years (these does have very low completions considering the age). Nested it is a compile error in newer Crystal. These are also poorly structured, lacks proper indents, and the reference solution is "one-liner". So, please consider improving them as well. If the reference solution is difficult to understand, and prevents upgrade, replace with a better one.
