Tutorial Week 6 Task 1. Develop type-checking algorithms for the following language constructs, along the lines of the type-checking algorithm we developed in the lectures. • P+Q • while P do Q • repeat P until Q • let x : t = P in Q Task 2. Some languages have features like exceptions (which […]

### function.arity > Functions which manipulate the way functions work with their arguments. ——————————————————————————– #### arity **Signature:** `_.arity(numberOfArgs:Number, fun:Function)` Returns a new function which is equivalent to `fun`, except that the new function’s `length` property is equal to `numberOfArgs`. This does **not** limit the function to using that number of arguments. It’s only effect is

Algorithms and Data, Summer 1 2016 Problem Set 5 (last one!) Due June 22 at 9 PM Part I – All Together Now The following problems can be solved with either greedy, divide and conquer, dynamic programming, or network flow techniques. Choose one of those strategies to solve the problem, describe the steps of your
SCHEME and functional programming Dr. Jozo Dujmović Jozo Dujmović Functional Programming 1 Programming paradigms • Paradigm = fundamental style of programming. • Main computer programming paradigms are: 1. Procedural (imperative) programming 2. Nonprocedural (declarative) programming 3. Logic programming (subset of declarative programming) 4. Functional programming (subset of declarative programming) 5. Object-oriented programming Jozo Dujmović Functional

Distributed Systems COMP90015 2016 SM2 Project 1 – Multi-Server Chat System 1. Synopsis The assignment is about creating a “chat” application. The chat system consists of two main distributed components: chat servers and chat clients, which may run on different hosts in the network. The architecture of the system is presented in the following diagram.
