Masala: Shaxmat taxtasida ot va piyoda bor. Ot eng kam yurish bilan piyodani urishi kerak.
Ot eng kam necha qadamda piyodani uradi?

Masalani koâpchilik rekursiya yordamida yechib koârsatishdi. Men esa 9 sinf bolasi qanday yechganini yozib bermoqchiman.
Massiv (array) yasab olamiz. taxta[8][8]
Ot turgan joyni 0 deb belgilaymiz. Endi massivning har bir katagidan yurib chiqamiz. Agar biror son koârsak, shu sondan borish mumkin boâlgan joylarni +1 qilib belgilab chiqamiz.
Demak, agar ot 0-raqamda turgan boâlsa, undan borish mumkin boâlgan joylar 1 ga aylanadi.
Bitta oâtishda butun taxtani toâldirib boâlmaydi. Shu sababli bajargan ishimizni bir necha marta takrorlaymiz. Necha marta takrorlash kerak? Aniq bilmaganim uchun oâsha payt 10 marta takrorlaganman. keyinchalik esa maksimum qadamlar sonini aniqlab, 8 martaga tushirganman.
2-oâtishda taxtamizda (massivda) 0, 1, va 2 sonlari paydo boâladi. Shu zaylda davom etamiz va 3 lar va 4 lar hosil boâlishini kuzatamiz.
Endi, Ot turgan joydan boshlab, keyingi raqamga qarab yurishni boshlasak har doim ham manzilga yeta olmaymiz. Chunki 0->1->2 dan keyin 3 ga oâta olmasligimiz mumkin.
Mana shu yerda men oârgangan bitta zoâr falsafa bor:
- Natija olish uchun har doim ham boshlangâich nuqtadan tugash nuqtasiga harakat qilinmaydi. Baâzida shunday holatlar boâladi, tugash nuqtasidan boshlanish nuqtasiga borish kerak.
Man hayron qolganman (shok boâlganman). Rostdan ham shunday ekan.
Agar ot turgan joydan biror keyingi songa oâtsam va yana ixtiyoriy keyingi onga oâtsam, men tugash nuqtasiga bora olmas ekanman.
Lekin, agar tugash nuqtasidan orqaga qaytishni boshlasam, ixtiyoriy kichik sonni tanlasam ham doim boshlangâich nuqtaga yetib kelar ekanman.
Shunday qilib, piyoda turgan joy 3 ga teng. U yerdan ixtiyoriy 2 ga oâtaman, keyin yana ixtiyoriy 1 ga va 0. Bu eng qisqa yoâl boâladi. Ishonmasangiz tekshirib koâring. Va agar yoâllar koâp boâlsa, shu usulda barchasini koârib chiqa olasiz.
Ana shunaqa gaplar.
đ Endi esa, uyga vazifa.
1. Ot turgan katak (manzil) va piyoda turgan katak (manzili) beriladi. Siz borish mumkin boâlgan barcha eng qisqa yoâllarni yozib bering.
2. Ot va piyodani shunday joylashtiring-ki. Ular orasidagi yoâl eng uzun boâlsin. Eng uzun masofa necha qadamli?

Telegram and Signal Havens for Right-Wing Extremists
Since the violent storming of Capitol Hill and subsequent ban of former U.S. President Donald Trump from Facebook and Twitter, the removal of Parler from Amazonâs servers, and the de-platforming of incendiary right-wing content, messaging services Telegram and Signal have seen a deluge of new users. In January alone, Telegram reported 90 million new accounts. Its founder, Pavel Durov, described this as âthe largest digital migration in human history.â Signal reportedly doubled its user base to 40 million people and became the most downloaded app in 70 countries. The two services rely on encryption to protect the privacy of user communication, which has made them popular with protesters seeking to conceal their identities against repressive governments in places like Belarus, Hong Kong, and Iran. But the same encryption technology has also made them a favored communication tool for criminals and terrorist groups, including al Qaeda and the Islamic State.
Export WhatsApp stickers to Telegram on Android
From the Files app, scroll down to Internal storage, and tap on WhatsApp. Once youâre there, go to Media and then WhatsApp Stickers. Donât be surprised if you find a large number of files in that folderâit holds your personal collection of stickers and every one youâve ever received. Even the bad ones.Tap the three dots in the top right corner of your screen to Select all. If you want to trim the fat and grab only the best of the best, this is the perfect time to do so: choose the ones you want to export by long-pressing one file to activate selection mode, and then tapping on the rest. Once youâre done, hit the Share button (that âless thanâ-like symbol at the top of your screen). If you have a big collectionâmore than 500 stickers, for exampleâitâs possible that nothing will happen when you tap the Share button. Be patientâyour phoneâs just struggling with a heavy load.On the menu that pops from the bottom of the screen, choose Telegram, and then select the chat named Saved messages. This is a chat only you can see, and it will serve as your sticker bank. Unlike WhatsApp, Telegram doesnât store your favorite stickers in a quick-access reservoir right beside the typing field, but youâll be able to snatch them out of your Saved messages chat and forward them to any of your Telegram contacts. This also means you wonât have a quick way to save incoming stickers like you did on WhatsApp, so youâll have to forward them from one chat to the other.
