Thanks for replying ,i understood where i did mistake.
can anyone help me with this? where am i getting this wrong .
I have tried multiple test-cases with all correct answers. I don’t know where I am getting wrong. It will be very helpful, if someone help me in finding the bug.
Consider the test input:
1 7 APAPAPP
Thank you for the correction!
But, I am still getting a SIGSEGV error (Runtime error). I tried to check for any divide by 0 error , but there is no such division. Also, memory usage is not too much. I don’t know why still I am getting such error .
Please link to your updated code.
It looks like you applied the fix, but then broke it by additionally switching to using a
std::string and using it wrongly
S is empty, so attempting to reference
S[i] is undefined behaviour.
Again thank you so much !
I just started solving practice questions, any tips or suggestion from you would be great.
- Set up
gccon your local machine
- Use debugging flags until you are ready to submit - I generally use
-D_GLIBCXX_DEBUG -fsanitize=undefined -ftrapv, which would have pointed out your Runtime Error immediately
- only use Codechef’s compiler when you are ready to submit, which you shouldn’t do until (at least) the sample testcase passes with the debugging flags enabled.
