OCaml Flashcards-OCaml Learning Flashcards

Example

Flashcard Front: 'let rec fact x = if x = 0 then 1 else x * fact (x - 1)' Flashcard Back: 'What does this function do?' Answer: 'This is a recursive function that calculates the factorial of a number.'

Scenario

This type of flashcard helps beginners understand recursive functions and conditionals in OCaml, crucial for mastering functional programming paradigms.

Example

Flashcard Front: 'List.fold_left' Flashcard Back: 'How is fold_left used in list processing and what are its parameters?' Answer: 'fold_left is a function that iterates over a list from left to right, applying a function to accumulate a result.'

Scenario

Useful for intermediate users who need to familiarize themselves with the OCaml Standard Library's tools for effective list management.

Example

Flashcard Front: 'Implement a binary search tree in OCaml.' Flashcard Back: 'type 'a bst = Empty | Node of 'a * 'a bst * 'a bst' let rec insert x = function | Empty -> Node(x, Empty, Empty) | Node(y, left, right) -> if x < y then Node(y, insert x left, right) else Node(y, left, insert x right)' Question: 'Explain how insertion works in this tree.'

Scenario

Advanced learners can deepen their understanding of OCaml's type system and recursive data structures, essential for algorithmic problem solving.

Example

Flashcard Front: 'Use of pattern matching in OCaml.' Flashcard Back: 'Provide an example where pattern matching is effectively used in error handling.' Answer: 'match result with | Ok value -> ... | Error msg -> ...'

Scenario

This flashcard would benefit developers looking to adopt idiomatic OCaml practices, particularly in robust error management.
