Our New Zealand Mint | Agoro Harry Potter Trading Coins just sold out in 62mins ?? This release joins the ranks of our previous sell outs of Star Wars, DC and Marvel collections. Some of these are now reselling on eBay for 83x. A new experience for me all this selling out stuff...have to rethink how you market quite a bit. Each release (and we do up to five a week) is a bet not only in terms of product, but also the marketing investment. How much do you lean in if you suspect it's going to sell out anyway? And what kind of messages do you release when the moment could be over very quickly? What do you do about collectors that miss out? How do you balance reseller vs end customer demand? Lots to think about ?? Check out the Harry Potter Trading Coins below. https://lnkd.in/gfDCCTFu #Agoro #Collectibles

Puzzle \| Bag of Coins Puzzle: Ishita has 10 bags full of coins. Each bag contains 1000 coins. But one bag is full of forgeries, and she just can t recall which one. She does know that genuine coins weigh 1 gram, but forgeries weigh 1.1 grams. To hide the fact that she can t recall which bag contains forgeries, she needs your help. How can she identify the bag with the forgeries with just one weighing? Solution: It is known that there is only one bag with forgeries. To identify that bag, Ishita can follow a simple procedure. She should take out 1 coin from the 1st bag, 2 coins from the 2nd bag, 3 coins from the 3rd bag and similarly 10 coins from the 10th bag. Now she should simply weigh all these picked coins together. If there were no forgeries, then the total weight should be \(1+2+3+ . . . +10\) = 55 grams. Now, if the total weight comes out to be 55.3 then she can conclude that the 3rd bag contain forgeries. So, if the total weight is \(55.n\), then it is clear that the nth bag contain forgeries. Youtube video: https://lnkd.in/dUrCCY7v \#nikolays_genetics_lessons

Hello everyone #37 - ???????????????? ???????????????? 151 ?????????????????? ??-?? - Mohd Fahad Feel free to ask if there are any queries and do share your ideas too. ??. ?????????????????????????? ? https://lnkd.in/gwPjn5vC? ?????????? ?????????? ??(1)? return max(a1,a2)+max(a3,a4)+max(a5,a6) ???????? ???????? ? https://lnkd.in/gtwDUSk3 ??. ?????????????????????????? ?????? ?????? ? https://lnkd.in/gbwRV9Uy? ???????????? ??(N) keep on using 0 coins up to N coins if it is possible to buy then print ans and return at that step else -1. ???????? ???????? ? https://lnkd.in/gwWMT5v8 ??. ?????????????? ???????????? ? https://lnkd.in/g8YMaCC9? ???????????? ??(??) First Observe that you can switch all 1 to 0 and all 0 to 1 to have our answer. Now let the flip for 1 to 0 be x. Then if i do x+2 flip i can just flip again anyone twice and still get all same. So ans will be x, x+2, x+4, x+2*k, and same for y(the flip form 0 to 1) be y, y+2, y+4, y+2*u. To keep on what value can be used i implemented using a map. Then just give the count of value whose map is non zero. ???????? ???????? ? https://lnkd.in/gy8G4t_6 ??. ???????? ???????? ? https://lnkd.in/gpTtUMqg? ???????????????????????????? ??(??) Two balls will intersect when a1/b1>a2/b2. Hence i used a stack to keep count of how many balls are left in stack finally. If the current top ball in stack reaches after our current ball in interation then pop otherwise just push the current ball in stack. Here we can see that stack will have balls that do not intersect at all times. ???????? ???????? ? https://lnkd.in/g8xeJ3qa ??. ???????????????? ???????????? ? https://lnkd.in/gWdfBzjb? ?????????????? ??(1)? Just see that X1=0, X2=A, X3=B, X4=A+B, X5=2B, X6=2B+A….. We can just say that if i is even then Xi=((i/2)-1)*B+A, if odd then Xi=(i/2)*B. Now this looks much better to see that if A=n*B+rem; then sorted X will be 0, B, 2B, 3B……….(n-1)B, nB, nB+rem, (n+1)B. (n+1)B+rem….. And so on. print the kth element of this pattern. ???????? ???????? ? https://lnkd.in/ghGE-8m8 ??. ???????????????? (????????) ? https://lnkd.in/gD9fu572? ???????????? / ???????????????????????????? ??(??)? first i will do for player1, Now for any point i will find the prefix score and suffix score. In the end just give abs( (pref+suff of player1) - (pref+suff of player2)).? ???????? ???????? ? https://lnkd.in/gZ4Ear-X ??. ???????????????? (????????) ? https://lnkd.in/gWyun2HN ???????????? / ???????????????????????????? ??(??*??)? first i will do for player1, I will have 4 prefix kinda matrix like if i need to find anser for (i,j), It will give answer (0,0) to (i,j) and (0,m-1) to (i,j) and (n-1,0) to (i,j) and (n-1,m-1) to (i,j) then we remove the extra using suffix prefix as used in Shooting easy. ???????? ???????? ? ???????? ???????????? ???????? ?????????? ??????????????????.
