Find the coordinates of a point A, where AB is the diameter of a circle whose centre is `(2,\ 3)` and `B` is `(1,\ 4)`.

Explanation

To find the coordinates of point A, where AB is the diameter of a circle with center O at (2, 3) and point B at (1, 4), we can follow these steps:

### Step 1: Understand the relationship between the points
Since AB is the diameter of the circle, the center O is the midpoint of line segment AB.

### Step 2: Use the midpoint formula
The midpoint M of a line segment with endpoints (x1, y1) and (x2, y2) is given by the formula:
\[
