i am getting sigsegv error in this coe when i am submitting it on codechef can anyone one help please

Hi Akash, you can get some help here: http://discuss.codechef.com/questions/7589/why-do-i-get-a-sigsegv

i recommand using static allocation, not dynamic one. bounds are faster to check, and there is no surprise : if it takes to much memory, you’ll see it from the first run. :slight_smile:

take care of array bounds…

sometimes you try to access the invalid index which mainly creates this problem…
also learn it from FAQ
