"Pyramid" is infinite.
"Pyramid" is two-dimensional (triangle).
(row, pos) - function parameters.
row - top row number ranging from zero,
pos - brick number from left to right ranging from zero.
Brick weight - 1 kg.
Every brick equally presses the bricks underneath.
1/2 to the left brick and 1/2 to the right.
If the brick pressed above with the total mass of 100 kg than the pressure is distributed evenly on the bottom bricks.
Required: implement function weight that calculates the pressure on the brick on the row, pos position.
Testing values:
weight(0, 0) => 0
weight(1, 0) => 0.5
weight(1, 1) => 0.5
weight(2, 0) => 0.75
weight(2, 1) => 1.5
weight(2, 2) => 0.75
weight(3, 0) => 0.875
weight(3, 1) => 2.125
weight(3, 2) => 2.125
weight(3, 3) => 0.875
