Q3.The weight of a sequence a0, a1,…,an-1 of real numbers is defined as a0 + a1/2 + ..... + an-1/2n-1. A subsequence of a sequence is obtained by deleting
some elements from the sequence, keeping the order of the remaining elements
the same. Let X denote the maximum possible weight of a subsequence of
a0, a1,..., an-1. Then X is equal to
