Step by Step solution about How to resolve the algorithm Function definition step by step in the Haskell programming language

In this code, the multiply function is used to multiply two numbers. The first line defines the function as multiply x y = x * y, which takes two arguments and returns the product of the two numbers. The second line defines the function as multiply = (*), which is a more concise way of writing the same function. The third line defines the function as multiply = \ x y -> x*y, which is a lambda expression that is equivalent to the first two definitions.

Here is a breakdown of the code:

• multiply x y = x * y: This line defines the multiply function. The function takes two arguments, x and y, and returns the product of the two numbers.
• multiply = (*): This line defines the multiply function as a synonym for the multiplication operator *. This means that multiply does the same thing as *, but it can be called as a function.
• multiply = \ x y -> x*y: This line defines the multiply function as a lambda expression. The lambda expression takes two arguments, x and y, and returns the product of the two numbers.

All three definitions of the multiply function are equivalent. Which definition you use is a matter of preference.

multiply x y = x * y


multiply = (*)


multiply = \ x y -> x*y
