Jan 20, 2023 · Given an array, the task is to determine whether an array is a palindrome or not. Examples: Input: arr[] = {3, 6, 0, 6, 3} Output: Palindrome Input: arr[] = {1, 2, 3, 4, 5} Output: Not Palindrome . Approach: Initialise flag to unset int flag = 0. Loop the array till size n/2; In a loop check if arr[i]! = arr[n-i-1] then set the flag = 1 and break

Mar 20, 2019 · You could check if the array is palindrome by comparing it with reversed copy of the original array. Using ArrayUtils.reverse from Apache commons: int[] arrCopy = Arrays.copyOf(array, array.length); ArrayUtils.reverse(arrCopy); boolean isPalindrome = Arrays.equals(array, arrCopy);

Dec 30, 2018 · Given an array arr[]. The task is to check if the array is PalinArray or not i.e., if all elements of array are palindrome or not. Examples: Input: arr[] = [21, 131, 20] Output: false Explanation: For the given array, element 20 is not a palindrome so false is the output. Input: arr[] = [111, 121, 222, 333, 444] Output: true

May 29, 2014 · Write a method isPalindrome that accepts an array of Strings as its argument and returns true if that array is a palindrome (if it reads the same forwards as backwards) and /false if not. For example, the array {"alpha", "beta", "gamma", "delta", "gamma", "beta", "alpha"} is a palindrome, so passing that array to your method would return true.

Feb 22, 2017 · You can use this method also to check if the string is palindrome or not. public static boolean pallindrom(String S) { char arr[] = S.toCharArray(); int flag = 0; for(int i = 0 ; i < (arr.length+1)/2 ; i++) { if(arr[i] != arr[arr.length-1-i]) { flag = 1; break; } } if(flag == 0) return true; else return false; }

Apr 17, 2025 · Palindrome program in Java – Here, we will discuss the various methods to check whether a given number is a palindrome or not. A compiler is added so that you can execute the program yourself, alongside various examples and sample outputs are given.

Aug 25, 2021 · Given a positive integer array arr of size N, the task is to check if number formed, from any arrangement of array elements, form a palindrome or not. Examples: Input: arr = [1, 2, 3, 1, 2]

Mar 11, 2015 · First you're not checking if a number is a palindrome or not. Your algorithm is flawed; Second, you're asking to enter a size but in the end, the user inputs it but you don't use it yourself. Instead, you're using that introduced value in …
