#算法
经过这一周密集的刷力扣题目,以及看别人总结讲解思路,我感觉编程能力是有长进的,有些题目我之前做过,现在掌握了套路之后再看以前的做法惨不忍睹。

例如:https://leetcode.cn/problems/longest-substring-without-repeating-characters/ ,左边是以前的实现(大概35行),右边是我掌握了思路之后的实现(大概20行),明显简洁了很多。

我打算以后即便不准备面试了,也把做算法题当成一个智力游戏来经常玩玩。

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. It recently surged to a cycle high of more than 1.60% after starting the year below 1%. 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. Rising interest rates amid a strengthening economy "may prove no challenge at all for stocks," Paulsen said.

The messaging service and social-media platform owes creditors roughly $700 million by the end of April, according to people briefed on the company’s plans and loan documents viewed by The Wall Street Journal. At the same time, Telegram Group Inc. must cover rising equipment and bandwidth expenses because of its rapid growth, despite going years without attempting to generate revenue.
