Given, two binary number A and B (A > B). Each of A and B can have at most 10^5 digits. You have to calculate (A^2 — B^2). [Here, (A^2) denotes the A power of 2].
What should be the approach to calculate A^2?

Suppose, there's n persons A1,A2,....,An. Person Ai have a set of p_i_ numbers, Xi.1,Xi.2,....,Xi.pi. You have Q quaries. Each quary is two types.
1 in t S1 S2 .... St.
Set p_in_ with t and Xi with S.
2 l r m S1 S2 ... Sm.
Calculate the number of people Al...Ar, who has at least one number Si in his set p_i_
1<=n,Q<=100000
1<=p_i_,t,m<=20
1<=Si,each element of Xi<=1000000
How can be it solved?
N.B.: Its a problem of an onsite contest occured 2 weeks ago.
