Simple functions working with list
Implement following functions:
- Create a function that computes length of a list.
length :: [a] -> Int
- Create a function that sums the list of integers.
sumIt :: [Int] -> Int
- Create a function that returns the first element in the list.
getHead :: [a] -> a
- Create a function that returns the last element in the list.
getLast :: [a] -> a
- Create a function that returns the list without the first element.
getTail :: [a] -> [a]
- Create a function that returns the list without the last element.
getInit :: [a] -> [a]
- Create a function that merge two lists into one list.
combine :: [a] -> [a] -> [a]
- Create a function that reverse a list.
reverse :: [a] -> [a]
- Create a function that merge two lists into one list.
combine :: [a] -> [a] -> [a]
- Create a function that product scalar multiplication if two vectors.
scalar :: [Int] -> [Int] -> Int
- Create a function that find the smallest element in the list. Consider input restrictions.
minimum :: [a] -> a -- Is this right?
- Find all prime divisors of a given number.
divisors :: a -> [a]
