Selgitage teksti tüübi kontseptsiooni Go keeles ja selle peamised omadused.

In the Go language, the string type represents an immutable sequence of bytes, commonly used to store text encoded in UTF-8.

Main features of strings in Go:

• Immutability: Once created, a string cannot be changed. Any operation that modifies the string creates a new one.
• UTF-8 encoding: Strings are stored in UTF-8, allowing work with multilingual text.
• Access by bytes: Indexing a string returns a byte, not a character (rune). To work with characters, the rune type is used.
• Slice support: Substrings can be obtained using slices, e.g., s[0:5].

Example of working with strings and runes:

s := "Привет"
fmt.Println(len(s)) // number of bytes
for i, r := range s {
    fmt.Printf("%d: %c\n", i, r) // prints byte index and character
}

Thus, strings in Go are a convenient and efficient way to work with text, but it is important to understand the difference between bytes and characters.
