Как bytes.FieldsFunc обрабатывает последовательности разделителей

Метод bytes.FieldsFunc рассматривает последовательности разделителей как одно место разбиения. То есть, если между двумя разделителями нет других символов, метод не создаст пустой подмассив между ними. Это поведение позволяет эффективно разделять строки, игнорируя лишние разделители.

Пример кода:

package main

import (
"bytes"
"fmt"
)

func main() {
input := []byte("apple,,orange,,banana")
result := bytes.FieldsFunc(input, func(c rune) bool {
return c == ',' // Разделяем по запятым
})
fmt.Println(result) // [[97 112 112 108 101] [111 114 97 110 103 101] [98 97 110 97]]
}

How Does Bitcoin Work?

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.”
