Functions

GenerateFillInTheBlankProblems(cards []FlashCard) []FillInTheBlankProblem

This function takes a slice of FlashCards, and returns a slice of FillInTheBlankProblems generated from the sentences in the FlashCards. It maps over each FlashCard and generates problems for each sentence in Sentences.

generateChoices(words []string, ans string) []string

This recursive function selects 4 random choices from the slice of words and return them as a slice. The correct answer is also included among the choices. If the correct answer is not among randomly selected words, the function recursively calls itself until it gets 4 choices including the correct answer.

GenerateMultiChoiceProblems(cards []FlashCard) []MultiChoiceProblem

This function takes a slice of FlashCards, and returns a slice of MultiChoiceProblems generated from the definitions of the FlashCards. It maps over each FlashCard and generates a MultiChoiceProblem using a random definition as the Question, four randomly selected words including the correct word as multiple choices for the question, and the correct word itself as the Answer.
