The strings package in Go

Trimming, splitting, joining, and building text.

func textOps(input string) (string, int, []string) {
    trimmed := strings.TrimSpace(input)
    upper := strings.ToUpper(trimmed)
    count := strings.Count(trimmed, "o")
    parts := strings.Split(trimmed, " ")

    var b strings.Builder
    for _, part := range parts {
        b.WriteString(strings.Title(part))
    }
    joined := strings.Join(parts, "-")
    _ = upper
    return joined + b.String(), count, parts
}

How it works

1. TrimSpace, ToUpper, and Count inspect text.
2. Split and Join convert to and from slices.
3. strings.Builder concatenates efficiently.
