Write a Java program to find the next smallest palindrome.Sample Solution: Java Code:import java.util.*; class solution { public static int nextPalindromeGenerate(int n) { int ans=1, digit, rev_num=0, num; //For single digit number, next smallest palindrome is n+1 if(n<10) { ans=...
Determine whether an integer is a palindrome. An integer is a palindrome when it reads the same backward as forward. Example 1: Input: 121 Output: true Example 2: Input: -121 Output: false Explanation: From left to right, it reads -121. From right to left, it becomes 121-. Therefore ...
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, if ...
