The problems of the Western and Moscow Subregional Contest before 2021 (included) can be found in the Yandex Contest System. But I can't find the problems of 2022 and 2023. I can only find problems of Northern/Southern subregional contest 2022/2023 in CF gym.
Edit: Western 2022/2023 use the same problem set as Northern Subregional Contest 2022/2023. What about Moscow subregional Contest 2022/2023?
Edit2: Moscow Subregional Contest 2022 can be found at https://qoj.ac/contest/1329.
Edit3: Where can I find Moscow subregional Contest 2023?
Western subregional uses the problemset of Northern subregional since 2022, possibly with minor changes
Thanks for this information!
I think QOJ has Moscow subregional 2022/2023.
