• Retire 2. Truncate a string!
• Retire 3. Limit string length - 1 after moving C# and Rust translations to 1.

Filling gaps

• Move C# translation from 3. to 1.
• Move Rust translation from 3. to 1.

Kata 1. and 2. are exact duplicates, and kata 3. is a bit simpler w.r.t. edge cases and I think it's similar enough to get deduplicated in this group.

I think i'd keep 1. due to having more languages than the others, and retire 2. and 3.
