I'm writing a for-loop statement, and I need to initialize two local variables to represent the indexes of strings a and b passed to the addBinary function. However, it's not allowed to put 'ia--, ib--' at the third position of for-loop. Is there an elegant way to do this?

func addBinary(a string, b string) string {
    for ia, ib := len(a)-1, len(b)-1; ia >= 0 && ib >= 0; ia--, ib-- {
        // some code
    }
}
