Arithmetic mean/Program/Natural memory unit/Exercise

Write a computer-program (pseudocode) which computes the arithmetic mean of two given non negative rational numbers.

• The computer has as many memory units as needed, which can contain natural numbers.

• It can add the content of two memory units and write the result into another memory unit.

• It can multiply the content of two memory units and write the result into another memory unit.

• It can print contents of memory units and it can print given texts.

• There is a stop command.

The initial configuration is

$(a,b,c,d,0,0,0,\ldots )$

with ${}b,d\neq 0$. Here ${}a/b$ and ${}c/d$ represent the rational numbers from which we want to compute the arithmetic mean. The result should be printed (in the form numerator denominator) and then the program shall stop.
