(33S) Partitions & Discrete Partitions
For positive integer input N programme P returns the number of partitions of N, programme Q returns the number of partitions in discrete parts (same as in purely odd parts).

For info on partitions see

https://en.wikipedia.org/wiki/Partition_(number_theory)

Improvements to programme most welcome.
