SPOJ Solve list comparison tool

Check this:

This is a tool for comparing solve list between two users in SPOJ... Of-course you can do that with your eyes, but that's no doubt tedious...

http://www.cise.ufl.edu/~mlpalii/spoj/head2head.pl?user1=<user_id_1>&user2=<user_id_2>

This is the address of the tool.... You just need to replace the <user_id_1> and <user_id_2> with your desired two spoj user ID.

Example: say, two users "zobayer" and "shiplu", their head2head comparison is here:
http://www.cise.ufl.edu/~mlpalii/spoj/head2head.pl?user1=zobayer&user2=shiplu
