Hey, even i also think there was some bug.
See this code : Solution: 48199198 | CodeChef (RTE)
and see this code : Solution: 48199198 | CodeChef (AC)
Only difference is that I changed the size of vector v from nm to nm+1 … but i have to take input till n*m-1 index only. I don’t know why this happened.

Btw what was the time complexity of your code? RealBin problem’s time constraint was fine if you used the correct logic.

Man there was a bug definitely! I tried to submit a solution that did not contain any logic ( to verify whether there was a bug or not), just inputs from user and submitted it (in java)…still I was getting TLE… :cry:

13

It TLEd for me for a o(1) logic ;__; (power of 2 with bit check)

14

it is same for cf and cc

15

lamest excuse bro .but u need to keep in mind how that effects coders .

today they wasted time .

from tomrrow they will keep on submitting tle solution again and again hoping that will pass .

if this is such an obvious and expected behavior then u should have considered time limits based on this

16

I was also giving contest. It is the real reason. I am not telling any excuse

In codeforces there is an instant plagarism checking then why not on codechef. If you are comparing codechef with codeforces then do it properly.

bro codechef is good for cheaters only . if u are trying honsetly u will most probably have hard time .

just copy solutions , codechef will look like best place :joy: . and u can brag everywhere

But in long challenges I think load on server is not high then also same problem was there with one of my friend in April Long Challenge.
