I'm trying to solve exercises where I am required to use recursion. I wrote this:static String reverse(String word){    if(word.length()<2){        return word;    }    else{        int index = word.length() - 1;        return word.charAt(index) + reverse(word.substring(0, index));    }}But the answer for that question was the following code:static String reverseRecursively(String str) {    //base case to handle one char string and empty string    if (str.length() < 2) {        return str;    }    return reverseRecursively(str.substring(1)) + str.charAt(0);}And now let's suppose that you are a recruiter and got the first solution. Do you accept it? If not, why? What should I do better?
Reversing strings using recursion
java;strings;recursion;interview questions
In production Java code, you would never reverse a string using recursion, primarily due to efficiency concerns, and also because new StringBuilder(str).reverse().toString() is better.  Therefore, this question should be treated as an academic exercise  a quick test to weed out candidates who don't understand recursion at all.  I don't think that an optimal solution is required.Basically, your solution is good enough.  That saidI prefer your reverse() to reverseRecursively(), since I consider the recursion to be an implementation detail that doesn't need to be reflected in the name.str is a more appropriate parameter name, since the function doesn't care whether the string is a word or not.The way you sliced the string is less elegant than in the second solution.I find your brace style slightly irksome.  (Normally I wouldn't say anything about it, but given how little code I have been given to evaluate, I'm judging you on that.)  Try to stick to the obsolete official Java style guide or Google's Java style guide, which is a close derivative of it.
