Assuming weather is a well-formed nonempty array, which code snippet, when inserted independently into the blank in the following code, prints all of the elements of weather? (Choose all that apply.)
❌ A. int i = weather.length; i > 0; i-- ✅ B. int i = 0; i <= weather.length - 1; ++i ❌ C. var w : weather ✅ D. int i = weather.length - 1; i >= 0; i-- ❌ E. int i = 0, int j = 3; i < weather.length; ++i ❌ F. int i = 0; ++i < 10 && i < weather.length; ❌ G. None of the above Explanation: Option A is incorrect because on the first iteration it attempts to access weather[weather.length] of the nonempty array, which causes an ArrayIndexOutOfBoundsException to be thrown. Option B is correct and will print the elements in order. It is only a slight modification of a common for loop, with i<weather.length replaced with an equivalent i<=weather.length-1. Option C is incorrect because the snippet creates a compilation problem in the body of the for loop, as i is undefined in weather[i]. For this to work, the body of the for-each loop would have to be updated as well. Option D is also correct and is a common way to print the elements of an array in reverse order. Option E does not compile and is therefore incorrect. You can declare multiple elements in a for loop, but the data type must be listed only once, such as in for(int i=0, j=3; ...). Finally, option F is incorrect because the first element of the array is skipped. The loop update operation is optional, so that part compiles, but the increment is applied as part of the conditional check for the loop. Since the conditional expression is checked before the loop is executed the first time, the first value of i used inside the body of the loop will be 1.

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.
Telegram auto-delete message, expiring invites, and more
elegram is updating its messaging app with options for auto-deleting messages, expiring invite links, and new unlimited groups, the company shared in a blog post. Much like Signal, Telegram received a burst of new users in the confusion over WhatsApp’s privacy policy and now the company is adopting features that were already part of its competitors’ apps, features which offer more security and privacy. Auto-deleting messages were already possible in Telegram’s encrypted Secret Chats, but this new update for iOS and Android adds the option to make messages disappear in any kind of chat. Auto-delete can be enabled inside of chats, and set to delete either 24 hours or seven days after messages are sent. Auto-delete won’t remove every message though; if a message was sent before the feature was turned on, it’ll stick around. Telegram’s competitors have had similar features: WhatsApp introduced a feature in 2020 and Signal has had disappearing messages since at least 2016.
