{ asserttrue(palindromenumber.ispalindromestring(12321)); assertfalse(palindromenumber.ispalindromestring(123)); } let’s have a dry run of this code: step 1: convert the number to string: original = “12321” . step 2: reverse the string using the built-in method: reversed = “12321”...
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
