CODE
guys i am getting sigsegv from a very LONG time,
this code is running well locally
can someone pls help me find the bug ?

Vectors are 0-indexed

could you break it down another level ?
I am new

Uh… when you access v[1000], it actually asks for the 1001-th element, but your vectors are only of size 1000.

oh got it
thanks dude
very silly of me
