Hoping for positive delta :D

so basically,

  • check sum of all ( assuming that we do NO operation at all)
  • until the element is one, wee find the absolute value of the sum of difference array. After than, we do operation 2
  • Now, the element is one. We can compare our temporary answer witth this element

is that the idea behind that ?

maybe i am too retarded to comprehend the problem C solution. Can anyone give me the more detailed explanation about it??

So, i imagine it as like this. The optimal solution could be displayed as an array with elements of the array is either 1 or 2.

Let's call it arr with size of k. So, it'll be like 12111122111.... something

Now, we know that swapping a 12 to become 21 is the same as doing multiplication by -1 to the result. But, i don't see how this couuld works!!

Let's say that we have calculate the sum of the array 12111. Changing it to become 21111 doesn't fkin means that i could multiply it by minus 1, right???

So, where's the correlation between the actual answer and us knowing the correlation between swapping elements and negating the answer ???

Please, my fucking brain has fried for even thinking it.........

Good luck all :D

new year, new hope. Hoping positive delta

This might sounds unrelated, but what about the rating deflation ?. I mean like problem with rating 1600 in 2019-ish is way easier ( at least for me ) than 2024's one

hmnnn this is maybe sounds unrelated but would you also consider the deflation of the rating ? i mean like 2018's 1600-ish rated problem is way easier than the 2022/2023

I usually watched it whenever I got sudden stress. Watching his videos somehow comforts me. I could watch him for hours and not feel bored :D.
