Concise Conversion of Numeric Arrays to Delimited Strings in Go
In Go, efficiently converting []int arrays to custom-delimited strings can be achieved with concise one-liners.
For instance, to transform []int{1, 2, 3} to "1, 2, 3" with a comma delimiter, a succinct approach is:
strings.Trim(strings.Replace(fmt.Sprint([1, 2, 3]), " ", ", ", -1), "[]")
This method leverages the functions strings.Trim to remove square brackets, strings.Replace to insert the desired delimiter, and fmt.Sprint to convert the array into a string.
Alternatively, similar results can be obtained using strings.Join, strings.Split, or strings.Fields functions. For example:
strings.Trim(strings.Join(strings.Split(fmt.Sprint([1, 2, 3]), " "), ", "), "[]")
These methods exploit the ability to convert the array to a string, split it by spaces, and concatenate them back together with the custom delimiter.
By utilizing these techniques, developers can efficiently transform numeric arrays into custom-delimited strings in Go with a single line of code.
