Study Notes
Introduction to Computational Thinking - Discussion Session
- The session was held on September 12, 2024, at McMaster University.
- Shahab Asoodeh, from the Department of Computing and Software, led the session.
- Exercise 01 was due on September 15 at 11:59 pm.
Last Lecture Review
- Currying functions are techniques that translate functions with multiple arguments into a sequence of functions each taking a single argument.
- This essentially transforms an n-ary function into a sequence of unary functions.
- Interpreters execute Haskell codes line-by-line, while compilers translate them into optimized native machine code.
- Expressions are syntactic entities that represent values, and all functions qualify as expressions.
- The session revisited Curry's paradox and the liar paradox.
Data Types Review
- Data types are syntactic entities that represent collections of values of similar form.
- Examples of valid data types include
Integer,Boolean, andInt. - Invalid data types include
a,Integer !Integer,Integer⇥Integer,Integer !Integer!Integer,Integer !Integer!Integer!Integer, andIntX int. - The code
a:: Integerfollowed bya = “5”results in a type error. - There is a difference between product types and function types.
Function Review
- The function
f :: (Integer, Integer) !Integer.Integerhas input typeInteger X Integerand output typeIntegerfor both elements. - The function
g :: Integer !Integer !Integer.Integerhas input typeIntegerand output typeIntegerfor both elements. - The expression
f2inf :: Integer !Integer !Integeris a valid expression in Haskell.
