English alphabet iteration with symbol replacement according to specified rules

It is necessary to implement a program in Go that outputs the sequence of English alphabet characters from 'A' to 'Z' with the following transformations:

• Each character is printed on a separate line.
• Every third character is replaced by its position number in the alphabet (for example, the letter 'C' is replaced with the number 3).
• Every fifth character is replaced with the corresponding Russian letter with the same position (for example, the fifth letter 'E' is displayed as 'Д', since in the Russian alphabet 'А'-'Д' occupy positions 1-4).
• The fifteenth character ('O') is displayed as the string "Привет".

package main

import "fmt"

func main(){
    for i := 0; i < 26; i++ {
        position := i + 1
        char := rune('A' + i)
        if position == 15 {
            fmt.Println("Привет")
        } else if position%3 == 0 {
            fmt.Println(position)
        } else if position%5 == 0 {
            // Map the position to the corresponding Russian letter
            russianLetters := "АБВГДЕЖЗИЙКЛМНОПРСТУФХЦЧШЩЪЫЬЭЮЯ"
            if position <= len(russianLetters) {
                fmt.Println(string(russianLetters[position-1]))
            } else {
                fmt.Println(string(char))
            }
        } else {
            fmt.Println(string(char))
        }
    }
}
