AI translates the explanation and quiz text while preserving code and answer scoring.

Pinocchio defines an optimized entrypoint that parses account slices without the overhead of native `solana-program` deserialization.

rust
use pinocchio::{
    account_info::AccountInfo,
    entrypoint,
    ProgramResult,
    pubkey::Pubkey,
};

entrypoint!(process_instruction);

pub fn process_instruction(
    program_id: &Pubkey,
    accounts: &[AccountInfo],
    instruction_data: &[u8],
) -> ProgramResult {
    // Zero-allocation logic
    Ok(())
}
