🍳 Задача по Python #28

Описание

Даны два массива, inorder и preorder. Оба массива имеют размер n. В первом массиве хранятся значения узлов дерева в порядке обхода бинарного дерева поиска. Во втором массиве хранятся значения узлов дерева в порядке обхода в ширину. Из этих двух массивов нужно собрать изначальное бинарное дерево.

Примеры

build_tree([2,1],[1,2]) # [1,2]
build_tree([1,2],[1,2]) # [1,None,2]

Свой вариант решения в комментарии 💭
Кодом делиться через pastebin.org или repl.it.

Spiking bond yields driving sharp losses in tech stocks

A spike in interest rates since the start of the year has accelerated a rotation out of high-growth technology stocks and into value stocks poised to benefit from a reopening of the economy. The Nasdaq has fallen more than 10% over the past month as the Dow has soared to record highs, with a spike in the 10-year US Treasury yield acting as the main catalyst.

But according to Jim Paulsen, the Leuthold Group's chief investment strategist, rising interest rates do not represent a long-term threat to the stock market. Paulsen expects the 10-year yield to cross 2% by the end of the year. A spike in interest rates and its impact on the stock market depends on the economic backdrop, according to Paulsen.

Telegram Q&A
Q: How does hottg.com work?
Once you've set up a username, you can give people a hottg.com/username link. Opening that link on their phone will automatically fire up their Telegram app and open a chat with you. You can share username links with friends, write them on business cards or put them up on your website.This way people can contact you on Telegram without knowing your phone number.

With Telegram, you can send messages, photos, videos and files of any type (doc, zip, mp3, etc), as well as create groups for up to 200,000 people or channels for broadcasting to unlimited audiences. You can write to your phone contacts and find people by their usernames. As a result, Telegram is like SMS and email combined — and can take care of all your personal or business messaging needs. In addition to this, we support end-to-end encrypted voice calls.
