Custom Implementation of filter

	filter' :: (a -> Bool) -> [a] -> [a]
	filter' f [] = []
	filter' f [x] = if (f x == True) then [x] else []

Custom implementation of map in haskell (as practice)

	-- Custom implementation of map
	map' :: (a -> b) -> [a] -> [b]

coder3112 / PrimeFactorization.hs

Created July 2, 2022 17:25

Prime Factorization in haskell to return a list of tuples giving the divisor as well as the power it is raised to.

	-- Example:
	-- > pf 120
	-- [(2,3),(3,1),(5,1)] since 120 = 2^3 * 3^1 * 5^1
	-- Thanks to leftaroundbot on stackoverflow for helping me out.

	-- Tells us how many times a number can be divided by another
	-- Eg: >dividerPower 120 5
	-- 1
	dividerPower :: Integer -> Integer -> Int
	dividerPower n d
