why is it showing segmentation fault (SIGSEGV) for my solution:
Please either format your code or (better!) link to your submission - no one wants to squint at a PNG
Fails 100% reproducibly for me using the sample testcase:
echo "2 1 1 2 2 1 2 1" | ./a.out karthik2_1-RGAME.cpp:107:29: runtime error: member access within null pointer of type 'struct node' Segmentation fault (core dumped)
yes bro i know that, but why is it showing runtime error?, is there some problem in the logic?
