    --------------------------
    //First Pass/ Idea
    //define helper function (isNumValid())
      //if length is 1 and value is not 0
        //return true
      //if length is 2 and value does not start with 0 and val < 26
        //return true
    //take the first char/num in s and put it our helper func
    //if num is valid
      //call numDecodings again on the rest of string, not on what we just checked
