Many codes are going to fail system test today for the problem B of contest Codeforces round 717.Its my prediction,let's see what happens.

What if you are mohammedehab2002's alt account and you knew pretests were weak? :)
U might be right lol
I'm curious to know what motivated you to picking problem B as that special problem
This seems to always happen with bruteforce range condition problems, as people always submit cheese sols. But perhaps there is something more?
I failed it(I qualify as a cheese sol writer)can you tell me how not to approach such questions or how to do so. What to avoid and all.
In my case, I mistakenly wrote a[i] in place of a[j] at one place and still my code passed pretest 2 and 3.
The reason i came to know because usual b problems for which answer is boolena type i.e yes or no 10^4 test cases are checked,but today only 5 test setseach having maximum 15 with 1 having just 2 test cases thus total mybe max 62 which is very very very less number of test cases to be checked for boolean type problems.
CF FST-Predictor
I initially thought that Xor of array should be 0. I got wrong answer on pretest 3. I was thinking of a counter case and then realize of a countercase like this and corrected myself:
4
3 3 3 0
Guess what the above case was the hack XD.
That is why I did stress testing already.
How to do stress testing for a problem ?
You can check Errichto's tutorial.
Can you please give me link ?

Thanks <3
