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...4.13 LAB: JavaScript arrays Write the function divideArray() in script.js that has a single numbers parameter containing an array of integers. The function should divide numbers into two arrays, evenNums for even numbers and oddNums for odd numbers. Then the function should sort the two arrays and output the array values to the console. Ex: The function call: let nums = [4, 2, 9, 1, 8]; divideArray(nums); produces the console output: Even numbers: 2 4 8 Odd numbers: 1 9 The program should output "None" if no even numbers exist or no odd numbers exist. Ex: The function call: let nums = [4, 2, 8]; divideArray(nums); produces the console output: Even numbers: 2 4 8 Odd numbers: None Hints: Use the push() method to add numbers to the evenNums and oddNums arrays. Supply the array sort() method a comparison function for sorting numbers correctly. To test your code in your web browser, call divideArray() from the JavaScript console.
