Напиши функцию longest_word<'a>(a: &'a str, b: &'a str) -> &'a str, которая возвращает слово с наибольшей длиной из двух строк.
Но есть ограничение: ты не можешь копировать строки — только возвращать ссылку.
📌Пример:
fn main() { let s1 = String::from("pirate"); let s2 = String::from("gold");
let result = longest_word(&s1, &s2); println!("Longest: {}", result); // 👉 "pirate" }
🔍Подсказка: - Тебе нужно указать время жизни `'a` для всех аргументов и возвращаемого значения. - Если ты не укажешь 'a, компилятор не поймёт, какая ссылка может жить дольше. - Возвращать String нельзя — только &str (ссылка на строку).

Bitcoin is built on a distributed digital record called a blockchain. As the name implies, blockchain is a linked body of data, made up of units called blocks that contain information about each and every transaction, including date and time, total value, buyer and seller, and a unique identifying code for each exchange. Entries are strung together in chronological order, creating a digital chain of blocks. “Once a block is added to the blockchain, it becomes accessible to anyone who wishes to view it, acting as a public ledger of cryptocurrency transactions,” says Stacey Harris, consultant for Pelicoin, a network of cryptocurrency ATMs. Blockchain is decentralized, which means it’s not controlled by any one organization. “It’s like a Google Doc that anyone can work on,” says Buchi Okoro, CEO and co-founder of African cryptocurrency exchange Quidax. “Nobody owns it, but anyone who has a link can contribute to it. And as different people update it, your copy also gets updated.”
