Javascript

Assignment 1. In Javascript we are going to create a Class called Chain. If you need a little primer on creating objects and classes in Javascript see [login to view URL] - if you know your object oriented code this will be relatively straightforward. Your Chain will be made up of Links. Each link will have an id, a value (String) and a pointer to the next link ( NextLink ) - which is simply a pointer to the id of the next link in the Chain. Please note that this is a very inefficient representation of the Chain. Here is a simple Javascript code definition of a Link for you to use. [login to view URL] You will make a Chain consisting of 5 links. You will also create a print function for the chain that will print the links in link order. You may need to create some functions to support this functionality. Assignment 2. Implement a Stack computer in Javascript (you will turn in a link to your program in JSFiddle). This is a simple computer that keeps a stack, when a number is entered it goes onto the top of the stack. When an operation is entered, the previous 2 numbers are operated on by the operation. For example 2 [enter] 2 5 [enter] 5 2 * [enter] * 5 2 -> collapses to 10 would leave at 10 at the top of the stack. The program should use a simple input box, either a text field or prompt and display the contents of the Stack. Question: What kind of structure and algorithm is needed to make a game like this? Assignment 3 You are going to create a List. You will then fill it with numbers consecutively numbered from 2 to n where n is entered by the user. Create a second List - this one should be a Queue - it is empty. Once you have the first List filled we are going to use a technique called Sieve of Eratosthenes which uses first queue to fill the second queue. You will need to look at the algorithm for this [login to view URL] Here is the simple method to do this - L1 is the first list, Q1 is the Queue. 1. Go to 1st element in L1 (which will be 2). 2. Because it exists - Push this into Q1 and remove it from L1 3. Iterate through each element of L1 and if the value is divisible by 2 remove it. 4. When done go back to the beginning of the list (the value will be 3 the second time around) 5. Print Iteration 1, Value of L1 (all elements) and Q1 (all elements) 6. Repeat steps 2-5 with this new element - repeat until L1 is empty. Sample output with input 10 Iteration 0: L1 = 2 3 4 5 6 7 8 9 10, Q1 = , Iteration 1: L1 = 3 5 7 9, Q1 = 2 Iteration 2: L1 = 5 7, Q1 = 2 3 Iteration 3: L1 = 7, Q1 = 2 3 5 Iteration 4: L1 = , Q1 = 2 3 5 7
