Also why this is prompting “Submission not Judged”
Check here the code
Is there any problem with the sever (codingblocks) right now??
not the correct way to take input
fori(n){
forj(m){
cin>>v[i];
}
}
as v is vector of strings
so only one loop should run
also make ans vector of size n+1 X m+1
Modified code
NO there is no problem with server
thanks--------->>>>>>
i hope this helps
if yes hit a like and don’t forgot to mark doubt as resolved 
if you have more doubts regarding this feel free to ask
@asaurabh_26
One thing I didn’t understood was why we have to make array n+1 x m+1 as I am not going outside anywhere!!
Done!
thank you for suggesting correct method of input ( because I initially took char vector that’s why one extra loop remained there)
I marked the doubt as resolved!!
Regards
initially i did not look at solve() and it is giving segmentation fault so i just increase the size of array
to check what is wrong
you can ignore that
it will also work with nXm
