Thank You Very Much :pray: :pray: :pray:
I was stuck on this question from 6 days !!!
but I am still taking 0.9 seconds ? shouldn’t it be 0.3-0.5 sec at most

50

It depends. You can also use \n in place of endl for printing newline

Yes, use \n instead of endl. endl is slower because it forces a flush, which actually unnecessary.

CodeChef: Practical coding for everyone

this code is for 15 points only

56

the sample test cases don’t help much, try all possible combinations, check the video on youtube

57

its working for the sample testcases mentioned in the editorial above and other combinations which came into my mind too

58

Let me try, if I get something I’ll post it

Sorry I tried, but couldn’t find the problem, Its a hard question

59

Anyone please help me with this code, I checked my solution with all the cases and it is giving all correct answers as compared to the correct solution. Please tell me that, is the problem occuring due to mod or is due to any other edge test case.

As a beginner, this problem taught me to first understand the problem thoroughly and to only dive into coding when I’m absolutely sure of its implementation! A big thanks to the Admin!

61

Any test-case on which my code goes wrong (only for 15pts). It will be really helpful. Thank you :slightly_smiling_face:

You are not missing any test case.
You just need to print the sum as cout<<sum%mod<<endl;
mod=1000000007

63

Then also first sub-task should pass but it gives WA

64

it showing correct now

65

Can anyone help me to find out my mistake .It will be really helpful. Please…

i guess

67

Oh I thought it is some concept😅. BTW I used DP but only got 15 points, since it is using O(R) space which is 10^12, so it throws RuntimeError

68

I am so far not a great coder, looking at the question and after going through it I did get a know of almost all the edge cases but when i tried to code it… Ufff
The video editorial did help me understand the edge cases i missed but not how to go about the code…
Could anyone help me with a commented well written code please
