Write a Python program using the Turtle Graphics to draw the concentric circles as described below:

1. the radius of the inner circle is 50, and the radius of the outer circle is 100.
2. the two circles should be filled with different colors (as shown in the screenshot).
3. no straight line should be drawn between two circles (no movement track).
4. the turtle (cursor) should be hidden.

Hint: pay attention to the order in which the two circles are drawn (the newly drawn circle will cover on top of the previously drawn circle).
