Can someone please look why my program is giving Runtime error (SIGABRT).

Thanks in advance 
I haven’t read the entire solution, but I think the STL vector is storing too much of memory. The value of n can be 10^9 at max, which will make the vector overflow, thus giving the SIGABRT error.
Admin’s answer to this one seems to be pointing towards it only:

Hey hb11
Since vectors are defined for snakes & we have at most m=10^5 snakes, n is just the coordinate of snakes I don’t think there should be memory error since at most I am using 6*100010 (=600060 < 1000000) memory space.
