Predict mine. Maybe I prove you wrong. :)

Is D is solvable in O(1) complexity? 99220580

aaa -> bba -> cca

https://codeforces.me/blog/entry/77551 you can find the O(sqrt(k)) answer in the solution of perfect permutation.

check this case baaddabdaa. your output 4 babd 3 abd 4 aabd 3 abd 4 dabd 3 abd 2 bd 1 d 0 1 a correct output 6 baaabd 5 aaabd 4 aabd 3 abd 4 dabd 3 abd 2 bd 1 d 0 1 a

I don't know why this simple solution works 93280623. Is test cases are Weak?

Can anyone tell why my solution 82140244 shows WA on pretest 1?

Ok thanks, But why this happens as function may return any undefined value and as I am not using this value anywhere so it should work fine.

Why same code 79221325 passes on using c++17 but shows 79185573 MLE with c++17(64)?

can you please recheck why my solution is getting wrong answer in ONE23 because one of the accepted solution also does the same thing?

Plot Twist 17^6: Only output is provided and you have to find problem statement with input.

My solution check all the elements in nr set and select that number whose removal makes minimum change in current OR. It gives better answer 41. But it didn't get accepted in online round.

I think either this is an approximate problem or the tester solution is wrong.

Now the same code 60158338 passes upto test case 83.

Why my solution 60134423 passed pretest in 1954ms. But after system test it gets TLE on pretest8 ?

You have solve only 50 question in 10 months. Solve atleast 300 — 400 question and give some more contest.

OK Thanks

can anyone tell why my code https://codeforces.me/contest/1108/submission/48851718 for problem https://codeforces.me/contest/1108/problem/E1 shows wrong answer on online ide while it give correct answer in sublime text??
