--description--
The points P (x1, y1) and Q (x2, y2) are plotted at integer co-ordinates and are joined to the origin, O(0,0), to form ΔOPQ.
There are exactly fourteen triangles containing a right angle that can be formed when each co-ordinate lies between 0 and 2 inclusive; that is, 0 ≤ x1, y1, x2, y2 ≤ 2.
Given that 0 ≤ x1, y1, x2, y2 ≤ 50, how many right triangles can be formed?
--hints--
rightTrianglesIntCoords() should return a number.
assert(typeof rightTrianglesIntCoords() === 'number');
rightTrianglesIntCoords() should return 14234.
assert.strictEqual(rightTrianglesIntCoords(), 14234);
