excellent explanation thanks bro
can you please explain the formula? (r * (r + 1) / 2) - ((l * (l - 1)) / 2) + ((r - l + 1) * k) i got the first part but why are you doing (r - l + 1) * k?? thanks in advance
Because see The prev formula was 1+2+3+4....n Now i have to add k to all of the nums right Hence r - l + 1 is the number of numbers and i have to increase all by k

but why to run for min(2^n , k)
If k is very small then we will run for k operations But if k is very big, we run for 2n operations
thank you so much <3
Bro for test case - 5 2 100 1000 1000000. Output should be 7 right?
Ans shd be 5
@@formidablechief27 how bro? 1) 5 +2 = 7 2) 7+100 = 107 3) 107+100 = 207 4) 1000 +207 = 1207 5) 1000 + 1207 = 2207 6) 2207 + 1000000 = 1002207 7) 1000000 + 1002207 = 2002207 Total 7 operations.
@Tech-Tonic-Tales Op1 : 5 2 becomes 7 Op2 and 3 : 7 1000000 Op4 : 2000007 1000 Op 5 : 20000..7 100
why did you directly add ele and left ?
That was the part which took me most of the time during contest. So i wrote down a few cases and realised at the end how much ever k we have left, we can just buy whatever because we can buy inifnitely right. Suppose if my made array after buying is 1234 and my n is 4 And i have suppose 3 left So i can buy a 1, a 2, and a 3 and to add 3 more subarrays. Resulting in now 1 2 3 4 1 2 3 So adding left was giving right for all tests which i had made and hence i submitted that
Good explanation

I saw your cf profile. I was shocked that how much you grinded in such a short amount of time great work Also me got inspired from the numbers of question you have solved
hello bhai, thanks for this video, i could solve only A and B1, and was stuck at B2, this video really helped! Also, I am just starting to give contests in cf, in situations like these when i am not able to solve even half of the ques, should i just upsolve one ques? Is it fine? Just curious ki aapne kitne solve kiye... Once again thanks for this nice explaination...
Yes you upsolve those which u couldnt solve in contest Definetely helps before next contest I solved A B1B2 very fast but for C i couldnt figure out how to fix my tle
hey brother i started my cf journy 3 months back solved around 115 questions . when i participate in contest i could barely solve 1 question , so i get demotivated enough , just want to ask what are the min normal question i must solved to perform good in contest ,and after how many ques u started participating in cf contest ???

有中文吗
No
Amazing. Is there any specific type of intutation/prove behind it or this clicked by just observing TC?
Yup the samples had the clue that such procedure was to be followed. Plus i couldnt find any further combinations to make elements so i went forward with this
Please Explain D also
Once im able to solve it, i surely will !
That's amazing ✨✨
