A lot of people ask me how can they be as good** as me?
TIL, that I'm at no 25 in descending order of CPers/DSAers list with no of contests participated.
The method is really simple.
Head down and keep grinding.

My background when I got my first internship offer with a stipend -
- I did not know what is leetcode back then.
- 15 CodeChef contests
- 4 CodeForces contests
- No account on any other website except GitHub.
- 3-digit JEE rank if that counts?

If one follows JP CPers here. Some of them, after participating in a contest, regularly post their solns in Japanese here.
Not sure, how many times I will do it, but here are the solutions which I implemented for all problems of today's div 2.
CF Round 841
A -
Notice that it asks to find the maximum sum instead of the minimum sum. It's never optimal to have more than one > 1 element. Hence, the maximum possible sum of the array is prod(a)+len(a)-1.

I purchased a domain for personal homepage ~5 years ago with a hope of maintaining a blog.
I have been lazy so far. It has been a bare minimum html page with links of my socials.
In last ~24 hrs, I have ended up creating a website more than just an bare minimum html.

Round 845
A: Let b_i = a_i %2
Notice that product of 2 odd nos is odd and 2 even nos is even.
Now no of operations required is no of index i such that b_i == b_{i+1}

This was the first

contest where I spent time thinking about solving the problem using flow.
No of ACs made me believe that this problem can actually require flow.
Spoiler: I couldn't solve using flow, so I returned to greedy and got an AC.

Hello 2023
A: We need RL as a substring. Find the first index which has a different next element. If it's LR, swap them. RL we do not need an operation.
If no such index exists, the answer is -1.

GoodBye 2022
A: Each operation must be applied, and there is no operation after mth. b_m will be present on the whiteboard.
One can skip some b_i's by applying operation at b_m place.
Hence, answer is b_m + sum of largest n-1 elements in a[0...n-1] and b[0...m-2]

Equation reduces to y*2=n.
There if n is even, x=1 and y=n/2 is one of the solutions.

Then use std::reverse.
reverse(T.begin(),T.end())
Then check if they are equal S==T, take max length

has updated the profile to keep both old and new rating graphs.
I have way more red data points in the new rating graph than in the old one.
Also, the new graph is more flat than the old one, and my rating is red +- 30 for the last 3 years.

Ngl, I found it much harder.
Even tho I found very early that n^2,1,n^2-1,2,.., will form a continuous seq. I just filled it with the last row and column and tried to reuse soln of n-1 by rotating and mirroring the matrix.
Did all sorts of 🤡 things and got ac at 2nd last min.

A:
It's impossible if all elements are equal.
Sort in descending order.
If the largest no appears more than once. Insert the smallest no between them.
It works because, for any no other than first two, sum will be more than the largest element + 1
