Solution
Here is a step-by-step explanation of the Java program provided:
-
The program starts with the package declaration
package q22746;which is a way to group related classes. -
Then, it imports the
java.util.Scannerclass which is used to get input from the user. -
The
ArrayPalindromeCheckerclass is declared. This is the main class of the program. -
Inside this class, a static method
isPalindrome(int[] array)is declared. This method takes an array of integers as an argument and checks if the array is a palindrome. It does this by comparing the elements at the start and end of the array and moving towards the center. If at any point the elements are not equal, it returnsfalseindicating that the array is not a palindrome. If it successfully compares all pairs of elements without finding a mismatch, it returnstrue. -
The
mainmethod is where the program starts execution. It first creates aScannerobject to read input from the user. -
The program then asks the user to enter the size of the array and reads this value.
-
An array of the specified size is created.
-
The program then asks the user to enter the elements of the array one by one and reads these values.
-
The
isPalindromemethod is called with the input array as an argument. -
Depending on the result of the
isPalindromemethod, a message is printed to the console indicating whether the array is a palindrome or not.

Grace is fascinated by palindromic numbers and wants a program that accepts an integer as input and identifies the next smallest palindromic number that is greater than or equal to the input. Utilize a function called isPalindrome to check if a number is a palindrome and a function called findNext to find the next smallest palindrome.Note: This question helps in clearing technical coding tests for companies like Flipkart and Amazon.Input format :The input consists of an integer N, which represents the starting point for finding the next smallest palindromic number.Output format :The output displays an integer representing the next smallest palindromic number that is greater than or equal to N.Refer to the sample output for formatting specifications.Code constraints :The test cases will fall under the following constraints:1 ≤ N ≤ 105Sample test cases :Input 1 :130Output 1 :131Input 2 :52000Output 2 :52025Input 3 :99000Output 3 :99099Input 4 :1661Output 4 :1661Input 5 :1Output 5 :1Input 6 :100000Output 6 :100001Note :The program will be evaluated only after the “Submit Code” is clicked.Extra spaces and new line characters in the program output will result in the failure of the test case.
