You're like the last few pages of the book that gives all the answers

When I solved this issue on my own I didn't come to the idea of delete item from set. It's very graceful move. Thank you!

Hello!!!
Could you please make a video series on CSES Problem Set?

[junwang]

Since the input size and range are small, this is easier and more efficient:

def intersection(self, nums1: List[int], nums2: List[int]) -> List[int]:
arr = [0] * 1001
res = []
for n in nums1:
arr[n] = 1
for n in nums2:
if arr[n] == 1:
res.append(n)
arr[n] = 0
return res

Is it possible to buy premium from Europe ? Will entering US address and buying via Cash App work ?

[DenisBrilliantov]

I wonder if my solution in Swift would be accepted by an interviewer 

let set1 = Set(nums1)
let set2 = Set(nums2)
return


it is still O(n)

[DeathSugar]

Most optimal solutionfor Rust was just take two sets of those two input vectors and just call intersect

[barathkandapan]

Can't we just convert them to 2 sets and perform & over them
like
return set(nums1) & set(nums2)

1 - row solution : ) Like is guaranted

[juanmacias]

I got a faster time by breaking out early when the set is empty.

[kanishkkala]

How come he sees the cnt of dislikes, if that premium only is yes then that's absurd lmfaooo 1:08
