I'm interested in creating a digital personal assistant similar to Alexa and Siri, which can efficiently manage schedules. Specifically, I want to design a tool in Java that allows users to find events during a certain time period. This tool should also enable users to add and cancel events as their schedules change. To achieve this, I plan to use a SkipListMap class with specific operations (get, put, remove, subMap) and a DoublyLinkedList class. Additionally, I'll use the FakeRandomHeight class for debugging and testing. Could you provide guidance on how to approach this project, especially in terms of implementing the SkipListMap class and managing event data efficiently?

Description: In this project, you are required to make a java code to build a blockchain including multiple blocks. In each block, it contains a list of transactions, previous hash - the digital signature of the previous block, and the hash of the current block which is based on the list of transactions and the previous hash. If anyone would change anything with the previous block, the digital signature of the current block will change. When this changes, the digital signature of the next block will change. Detailed Requirements: 1. Define your block class which contains three private members and four public methods. a. Members: previousHash (int), transactions (String[]), and blockHash (int); b. Methods: i. Block( int previousHash, String[] transactions){} ii. getPreviousHash(){} iii. getTransaction(){} iv. getBlockHash(){} 2. Using ArrayList to design your Blockchain. 3. Your blockchain must contain genesis block and make it to be the first block. 4. You can add a block to the end of…

implement a grid transformation that reduces the size of the grid, while retaining the information in it in python 3 __init__(self, size: int): create a square 2-D grid of ints with size rows and size columns. Initialize all values to 0. set_value(self, i: int, j: int, val: int): set the value in the i-th row and j-th column to val. squish(self, k:int): Sum up the elements of k by k blocks of the grid. This method does not return anything, but rather modifies the grid object. The size of the modified grid is n / k where n was the original size. You can assume that the grid's size is divisible by k.
