In the Cartesian coordinate system xOy, the parametric equation of circle C is $$\begin{cases} x=cos\alpha, \ y=1+sin\alpha \end{cases}$$ (where α is the parameter). Establish a polar coordinate system with the coordinate origin O as the pole and the positive semi-axis of x as the polar axis. The polar coordinate equation of line l is ρcosθ - ρsinθ - 1 = 0. The distance from the center of circle C to line l is _____.
