public static boolean isPalindrome(String s) { String pureString = s.replaceAll(“[^A-Za-z0-9]”, “”); if(pureString.length() == 0) return false; October 25, 2014 at 3:26 pm Here is an easier solution using two pointers public static boolean isPalindrome1(String s) { s = s....
In this article, we have learned about palindrome in Java. Also, we discussed different Java programs that illustrate how to check if a given input is palindrome or not. The most straightforward way to achieve this is by using the built-in method of StringBuffer class named reverse().Amit...
}publicbooleanisPalindromeUsingStringBuffer(String text){Stringclean=text.replaceAll("\\s+","").toLowerCase();StringBufferplain=newStringBuffer(clean);StringBufferreverse=plain.reverse();return(reverse.toString()).equals(clean); }Copy In the code snippet, we invoke thereverse()method from theStr...
Here, we are implementing a java program that will read a string and check the palindrome words in string also find the occurrences of words in a given string. Submitted by Chandra Shekhar, on January 08, 2018 Given a string and we have to find occurrences of palindrome words using java ...
}returnbuffer.reverse().toString() +s; } The above solution is right, but it could have"exceed memory" problem when the string is toolong, since the check_board take O(n^2) memory. Inefficient Solution 2: publicclassSolution {publicString shortestPalindrome(String s) {if(s ==null|| s...
java Determine whether an integer is a palindrome. Do this without extra space. Some hints: Could negative integers be palindromes? (ie, -1) If you are thinking of converting the integer to string, note the restriction of using extra space. You could also try reversing an integer. However...
