I can see the imperative code in sorting algorithm, I'm intending to add in functional way
for e.g. In MergeSort , I can see while loop which is an iterative approach -
while (k < high + 1) {
// must check if empty to avoid exceptions
if (i > left.length - 1) {
array(k) = right(j)
j = j + 1
} else if (j > right.length - 1) {
array(k) = left(i)
i = i + 1
} else if (left(i) <= right(j)) {
array(k) = left(i)
i = i + 1
} else {
array(k) = right(j)
j = j + 1
}
k = k + 1
}
Best Practice: In scala, we follow functional way to write it
def merge(xs: List[Int], ys: List[Int]): List[Int] = (xs, ys) match {
// If either list is empty, return the other list
case (Nil, _) => ys
case (_, Nil) => xs
// If the first element of xs is smaller than the first element of ys,
// append it to the result of merging the rest of xs with ys
case (x :: xtail, y :: ytail) =>
if (x < y) x :: merge(xtail, ys)
// Otherwise, append the first element of ys to the result of merging xs with the rest of ys
else y :: merge(xs, ytail)
}
I'll be creating a PR shortly to add functional code for sorting algorithm given in this repo.
