❌ A. 1 ✅ B. 2 ❌ C. 3 ❌ D. Compilation error ❌ E. Runtime error ❌ F. None of the above
Explanation: In this code snippet, the processMap method uses the computeIfAbsent method of the Map interface. If the specified key is not already associated with a value (or is mapped to null), this method associates it with the result of the given function. In this case, the key "Two" is already present in the map with the value 2. Therefore, the computeIfAbsent method does not execute the provided function (k -> k.length()), and it returns the current value associated with the key "Two," which is 2. Option A might be tempting, but it is incorrect because the computeIfAbsent method doesn't execute the function when the key is already present in the map. Option B is the correct answer, representing the value associated with the existing key "Two." Options C and D are incorrect as there is no compilation error or runtime exception in this code. The behavior is as expected with the use of the computeIfAbsent method.

In general, many financial experts support their clients’ desire to buy cryptocurrency, but they don’t recommend it unless clients express interest. “The biggest concern for us is if someone wants to invest in crypto and the investment they choose doesn’t do well, and then all of a sudden they can’t send their kids to college,” says Ian Harvey, a certified financial planner (CFP) in New York City. “Then it wasn’t worth the risk.” The speculative nature of cryptocurrency leads some planners to recommend it for clients’ “side” investments. “Some call it a Vegas account,” says Scott Hammel, a CFP in Dallas. “Let’s keep this away from our real long-term perspective, make sure it doesn’t become too large a portion of your portfolio.” In a very real sense, Bitcoin is like a single stock, and advisors wouldn’t recommend putting a sizable part of your portfolio into any one company. At most, planners suggest putting no more than 1% to 10% into Bitcoin if you’re passionate about it. “If it was one stock, you would never allocate any significant portion of your portfolio to it,” Hammel says.
How To Find Channels On Telegram?
There are multiple ways you can search for Telegram channels. One of the methods is really logical and you should all know it by now. We’re talking about using Telegram’s native search option. Make sure to download Telegram from the official website or update it to the latest version, using this link. Once you’ve installed Telegram, you can simply open the app and use the search bar. Tap on the magnifier icon and search for a channel that might interest you (e.g. Marvel comics). Even though this is the easiest method for searching Telegram channels, it isn’t the best one. This method is limited because it shows you only a couple of results per search.
