Code to ::::implement a SnapshotArray that supports the following interface: SnapshotArray(int length) initializes an array-like data structure with the given length. Initially, each element equals 0. void set(index, val) sets the element at the given index to be equal to val. int snap() takes a snapshot of the array and returns the snap_id: the total number of times we called snap() minus 1. int get(index, snap_id) returns the value at the given index, at the time we took the snapshot with the given snap_id Example 1: Input: ["SnapshotArray","set","snap","set","get"] [[3],[0,5],[],[0,6],[0,0]] Output: [null,null,0,null,5] Explanation: SnapshotArray snapshotArr = new SnapshotArray(3); // set the length to be 3 snapshotArr.set(0,5); // Set array[0] = 5 snapshotArr.snap(); // Take a snapshot, return snap_id = 0 snapshotArr.set(0,6); snapshotArr.get(0,0); // Get the value of array[0] with snap_id = 0, return 5...
JAVA language, please add test screenshot public static int[] makeIntoPalindrome(int[] arr) Makes a palindrome from a given array by appending the smallest possible number of elements. For example, makeIntoPalindrome([1, 3, 7]) returns [1, 3, 7, 3, 1] makeIntoPalindrome([5, 4, 1, 3, 3, 1]) returns [5, 4, 1, 3, 3, 1, 4, 5] makeIntoPalindrome([1, 3, 3, 1]) returns [1, 3, 3, 1] makeIntoPalindrome([1, 4, 3, 2]) should return [1, 4, 3, 2, 3, 4, 1]. Parameters: arr - an array Returns: a new array that is a palindrome obtained by appending the fewest number of elements onto arr
