CF242E XOR on Segment

You've got an array $ a $ , consisting of $ n $ integers $ a_{1},a_{2},...,a_{n} $ . You are allowed to perform two operations on this array: 1. Calculate the sum of current array elements on the segment $ [l,r] $ , that is, count value $ a_{l}+a_{l+1}+...+a_{r} $ . 2. Apply the xor operation with a given number $ x $ to each array element on the segment $ [l,r] $ , that is, execute . This operation changes exactly $ r-l+1 $ array elements. Expression  means applying bitwise xor operation to numbers $ x $ and $ y $ . The given operation exists in all modern programming languages, for example in language C++ and Java it is marked as "^", in Pascal — as "xor". You've got a list of $ m $ operations of the indicated type. Your task is to perform all given operations, for each sum query you should print the result you get.

The first line contains integer $ n $ ( $ 1

For each query of type $ 1 $ print in a single line the sum of numbers on the given segment. Print the answers to the queries in the order in which the queries go in the input. Please, do not use the %lld specifier to read or write 64-bit integers in С++. It is preferred to use the cin, cout streams, or the %I64d specifier.
