        if(num < 10){
            return 1;
        }
        int nums = num%100;
        if(nums < 10){
            return translateNum(num/10);
        } else if(nums < 26){
            return translateNum(num/100) + translateNum(num /10);
        } else {
            return translateNum(num/10);
        }
    }
}
