Given a sequence {a<sub>n</sub>} with the sum of its first n terms denoted as S<sub>n</sub>, and it satisfies the equation S<sub>n</sub>=2a<sub>n</sub>−1.

1. Find the general formula a<sub>n</sub> for the sequence {a<sub>n</sub>}.
2. Let b<sub>n</sub>=$$\frac{n}{a\_n}$$, find the sum of the first n terms, T<sub>n</sub>, for the sequence {b<sub>n</sub>}.
