Write a method/function named shiftLeft( source, k) that shifts all the elements of the source array to the left by 'k' positions. You must execute the method by passing an array and number of cells to be shifted. After calling the method, print the array to show whether the elements have been shifted properly. Example: source=[10,20,30,40,50,60] shiftLeft(source,3) After calling shiftLeft(source,3), printing the array should give the output as: [ 40, 50, 60, 0, 0, 0 ]
- Assignment 5B: Maze Game! 2D Arrays can be used to store and represent information about video game levels or boards. In this exercise, you will use this knowledge to create an interactive game where players attempt to move through a maze. You will start by creating a pre-defined 2D array with the following values: :-, X","X"} "X","W"} "X","_"} "} 'X","X"} {"_" " "y" " " You will then set the player (represented by "O") at index 0, 0 of the array, the top-left corner of the maze. You will use a loop to repeatedly prompt the user to enter a direction ("Left", “Right", “Up", or “Down"). Based on these directions, you will try to move the player. If the location is valid (represented by “_"), you will move the player there If the location is out of bounds (e.g. index 0, -1) or the command is invalid, you will inform the player and prompt them to enter another direction If the location is a wall (represented by “X"), you will tell the user they hit a wall and the game is over. If the…Arrays: create an array of a given type and populate its values. Use of for loop to traverse through an array to do the following : to print the elements one by one, to search the array for a given value. ArrayList: create an ArrayList containing elements of a given type . Use some of the common ArrayList methods to manipulate contents of the ArrayList. Write methods that will take an ArrayList as its parameter/argument ; and/or return an ArrayList reference variable as its return type. Searching for an object in an Array: Loop through the ArrayList to extract each object and to check if this object’s attribute has a given value. Explain how and why interfaces are used in Java Collection Framework. Explain the major differences between a Stack and a Queue. Be able to use stack and queue methods. What is meant by O(N) notation? Express the complexity of a given code using the O(N) notation.Assignment 5C: Level Map Creator. There are a variety of ways that game developers store their level layouts. One simple method is to associate level elements with certain symbols, and then storing them in a 2D grid inside a text file. We will use our knowledge of 2D arrays to create a very simple Level Map Creator tool. The program should prompt the user to enter a width and height for the level. Then it should initialize a 2D array and fill every element with the *" symbol. Afterwards, the user should be given the following options via a menu: 1. Clear Level 2. Add Platform Prompt the user to enter a starting point and length for the Re-initialize the 2D array and fill every element with the "** symbol. horizontal platform. Replace those elements in the 2D array with the "=" symbol. If the length is longer than the number of columns |(or out of bounds), notify the user that this is not possible. Prompt the user to enter a column and row index. Replace that element in the 2D array…
