Encode and decode Base64 bytes

Java: Convert through UTF-8 explicitly before and after Base64 encoding.

Arduino / CBinary values & packets

Extract the low and high byte of a value

Arduino / C: lowByte and highByte expose the two bytes of a 16-bit value.

Arduino / C✓ Tested

RustErrors & optional values

Handle integer overflow without panicking

Handle integer overflow without panicking in a complete Rust program using the standard library.

Rust✓ Tested

C++Containers & compound values

Insert a map value only when a key is absent

C++: try_emplace preserves the old value when insertion does not take place.

Inspect components of a URI

Java: Use URI parsing instead of splitting a URL at punctuation manually.

RustErrors & optional values

Keep an optional value only when valid

Keep an optional value only when valid in a complete Rust program using the standard library.

Rust✓ Tested

Measure UTF-8 bytes separately from characters

Java: Encode a Java string before measuring its serialized byte length.

C++Ownership & optional values

Observe shared ownership without extending its lifetime

C++: A weak_ptr can be locked while an owner exists and becomes expired after the last owner is released.

C++Ownership & optional values

Own one dynamically allocated value with unique_ptr

C++: make_unique allocates a value whose lifetime is tied to its owning smart pointer.

Parse a UUID and inspect its version

Java: Use UUID.fromString for a standard UUID value.

C++Containers & compound values

Process a first-in first-out queue

C++: Queue exposes its front item separately from the operation that removes it.
