For some testcases I am getting a run time error while it runs fine on my local machine. Problem code. Any help would be awesome.

•  » » 9 months ago, # ^ |   +2 Given that it's been 6 months, I'm not sure the OP still needs help. But I would like to point out that 2 * 106 fits comfortably in 512MB.You were still right about the error though. The OP is creating an array of size N * X. N ≤ 103 and X ≤ 105, which means that 108 long longs will be created. This will cause MLE.

•  » » » » 8 months ago, # ^ |   0 The short answer is that you need to write a solution that uses less memory. That's what Memory Limit Exceeded means.The long answer depends on what solution you have right now.
•  » » » » 4 months ago, # ^ |   0 using Long long int here is causing the memory to exceed the limits , if u look at the constraints they can be met using int only so trying using int instead of long long int and that should solve the issue :)
•  » » » 6 weeks ago, # ^ |   0 Thanks a lot for the explanation about the memory usage, I was using long long as well while only using int was enough and in this case, required. I also got an example of not always using long long instead of int. Thanks

 » 4 months ago, # |   0 if u are writing a cpp code just dont use long long int , instead use int which takes less memory since MLE is the reason for runtime error . I did the same and it worked , thanks for this post though :)
•  » » 4 months ago, # ^ | ← Rev. 2 →   0 if u are writing a cpp code just dont use what you don't understand. long long is a 64-bit integer type while int is a 32-bit integer type (on most computers). This means an int can contain whole numbers up to an order of $10^9$ while long long can contain numbers up to something like $10^{18}$. If your solution may use numbers larger than $10^9$, you have to use long long.
•  » » » 4 months ago, # ^ |   +8 what you are saying is exactly correct , but the question he is talking about can be solved easily with int , which is why I suggested it , I suggested him to write int for the specific code, not in general. Although now that i am reading my own post it sounds wrong , nvm my bad. thanks
