Check if a string is a palindrome












14















I have a string as input and have to break the string in two substrings. If the left substring equals the right substring then do some logic.



How can I do this?



Sample:



public bool getStatus(string myString)
{

}


Example: myString = "ankYkna", so if we break it into two substring it would be:
left-part = "ank",
right-part = "ank" (after reversal).

Using LINQ and off course far from the best solution



var original = "ankYkna";
var reversed = new string(original.Reverse().ToArray());
var palindrom = original == reversed;

  • A string is inherently a character array, so the .ToCharArray() call is redundant.

  • @krillgar you're right, string implements IEnumerable<char> so the ToCharArray is not needed. I can't tell if it was like this back in 2012.

        This way is both concise in appearance & processes very quickly.

          It's also dead wrong, since it will always return false. s.Reverse() is an IEnumerable<char>, which never compares reference-equal to the original String (assuming the standard definition of Enumerable.Reverse and Object.Equals).

          If you just need to detect a palindrome, you can do it with a regex, as explained here. Probably not the most efficient approach, though...

            That is non-trivial, there is no built in method to do that for you, you'll have to write your own. You will need to consider what rules you would like to check, like you implicitly stated you accepted reversing of one string. Also, you missed out the middle character, is this only if odd length?



            So you will have something like:



            if(myString.length % 2 = 0)
            {
            //even
            string a = myString.substring(0, myString.length / 2);
            string b = myString.substring(myString.length / 2 + 1, myString.lenght/2);

            if(a == b)
            return true;

            //Rule 1: reverse
            if(a == b.reverse()) //can't remember if this is a method, if not you'll have to write that too
            return true;


            etc, also doing whatever you want for odd strings

                        Here is an absolutely simple way to do this,




                        1. Receive the word as input into a method.

                        2. Assign a temp variable to the original value.

                        3. Loop through the initial word, and add the last character to the reversal that you are constructing until the inital word has no more characters.

                        4. Now use the spare you created to hold the original value to compare to the constructed copy.


                        This is a nice way as u don't have to cast ints and doubles. U can just pass them to the method in their string representation by using the ToString() method.



                        public static bool IsPalindrome(string word)
                        {
                        string spare = word;
                        string reversal = null;
                        while (word.Length > 0)
                        {
                        reversal = string.Concat(reversal, word.LastOrDefault());
                        word = word.Remove(word.Length - 1);
                        }
                        return spare.Equals(reversal);
                        }


                        So from your main method,
                        For even and odd length strings u just pass the whole string into the method.

                            Since a palindrome also includes numbers, words, sentences, and any combinations of these, and should ignore punctuation and case, (See Wikipedia Article)
                            I propose this solution:



                            public class Palindrome
                            {

                            • The allowed list should certainly be extended to include more languages and concepts than just English, but I hope to illustrate that just checking if string.reverse() == string is not a complete solution to the palindrome problem.

                                This is a short and efficient way of checking palindrome.



                                bool checkPalindrome(string inputString) {

                                int length = inputString.Length;
                                for(int i = 0; i < length/2; i++){
                                if(inputString[i] != inputString[length-1-i]){
                                return false;
                                }
                                }

                                return true;

                                      I am pretty sure it was always the case, but people were so explicit when LINQ first came out. I just stumbled across this question and wanted to point that out to anyone else who came across your solid answer.

                                                                                                                              1. Receive the word as input into a method.

                                                                                                                              2. Assign a temp variable to the original value.

                                                                                                                              3. Loop through the initial word, and add the last character to the reversal that you are constructing until the inital word has no more characters.

                                                                                                                              4. Now use the spare you created to hold the original value to compare to the constructed copy.


                                                                                                                              This is a nice way as u don't have to cast ints and doubles. U can just pass them to the method in their string representation by using the ToString() method.

                                                                                                                                  2. Assign a temp variable to the original value.

                                                                                                                                  3. Loop through the initial word, and add the last character to the reversal that you are constructing until the inital word has no more characters.

                                                                                                                                  4. Now use the spare you created to hold the original value to compare to the constructed copy.


                                                                                                                                  This is a nice way as u don't have to cast ints and doubles. U can just pass them to the method in their string representation by using the ToString() method.
