❌ A. LinkedHashMap: {B=5, A=2, C=1, E=3, D=4}; TreeMap: {B=5, D=4, E=3, A=2, C=1} ❌ B. LinkedHashMap: {B=5, A=2, C=1, D=4, E=3}; TreeMap: {B=5, A=2, C=1, D=4, E=3} ❌ C. LinkedHashMap: {A=2, B=5, C=1, D=4, E=3}; TreeMap: {C=1, A=2, E=3, D=4, B=5} ✅ D. LinkedHashMap: {A=2, B=5, C=1, D=4, E=3}; TreeMap: {B=5, D=4, E=3, A=2, C=1} ❌ E. Error ❌ F. None of the above
Explanation: 1. LinkedHashMap Behavior: • LinkedHashMap maintains the insertion order of elements. • Here, linkedHashMap will display entries in the exact order they were inserted: {A=2, B=5, C=1, D=4, E=3}.
2. TreeMap with Custom Comparator: • TreeMap typically orders entries based on the natural order of keys, but here it uses a custom comparator to sort entries in descending order based on values from linkedHashMap. • Comparator.comparingInt(linkedHashMap::get).reversed() sorts treeMap by values in descending order, resulting in {B=5, D=4, E=3, A=2, C=1}.
3. Expected Output: • The LinkedHashMap output maintains the insertion order. • The TreeMap output shows entries sorted by values in descending order based on linkedHashMap values.

I have no inside knowledge of a potential stock listing of the popular anti-Whatsapp messaging app, Telegram. But I know this much, judging by most people I talk to, especially crypto investors, if Telegram ever went public, people would gobble it up. I know I would. I’m waiting for it. So is Sergei Sergienko, who claims he owns $800,000 of Telegram’s pre-initial coin offering (ICO) tokens. “If Telegram does a SPAC IPO, there would be demand for this issue. It would probably outstrip the interest we saw during the ICO. Why? Because as of right now Telegram looks like a liberal application that can accept anyone - right after WhatsApp and others have turn on the censorship,” he says.
What is Telegram Possible Future Strategies?
Cryptoassets enthusiasts use this application for their trade activities, and they may make donations for this cause.If somehow Telegram do run out of money to sustain themselves they will probably introduce some features that will not hinder the rudimentary principle of Telegram but provide users with enhanced and enriched experience. This could be similar to features where characters can be customized in a game which directly do not affect the in-game strategies but add to the experience.
