Secret Series of Integers

Four Intergers are encoded in a special manner. A encoded integer of any integer in a series is a difference between the sum of integers at the right of that interger and the sum of integers at the left of that integer. Suppose 1 2 3 4 are four integers in a series then 1 will be encoded as (2+3+4), 2 will be encoded as (3+4-1), 3 will be encoded as (4-(1+2)) and 4 will be encoded as (-(1+2+3)).
