How to convert an integer to its octal representation as a string in Golang?

In Golang, you can convert an integer to its octal representation as a string using the strconv package. Here's an example:

package main

import (
	"fmt"
	"strconv"
)

func main() {
	num := 42
	octal := strconv.FormatInt(int64(num), 8)
	fmt.Println(octal) // Output: 52
}

In this example, we use the strconv.FormatInt() function to convert the integer num to its octal representation. The second argument 8 specifies the base to use for the conversion, which in this case is octal. The resulting octal representation is stored in the octal variable and displayed using fmt.Println().
