Below image shows the output of the above longest palindrome java program. We can improve the above code by moving the palindrome and longest lengths check into a different function. However, I have left that part for you. :) Please let me know if there are any other better implementations ...

A palindrome is a word, phrase, number, or other sequence of characters which reads the same backward as forward, such as madam. Write a java program to find the longest palindrome present in a given string. For example, in the string a

Another method to check if a string is a palindrome or not is by using aforloop. Below are the steps to check if a string is a palindrome in JavaScript. functionpalindromeFn(string){conststringLength=string.length;for(leti=0;i<stringLength/2;i++){if(string[i]!==string[stringLength-1...

Have you consider that the string might be empty? This is a good question to ask during an interview. For the purpose of this problem, we define empty string as valid palindrome. 这道题没什么难的,就是考细心和对java的熟悉了,从两头往中间数,碰到非数字或letter的要跳过。 注意几点 1.当跳过...
