Use binary reflected Gray code (RGC) to determine how a 16-node linear array can be mapped to a 4-D hypercube. You must derive the 4-bit Gray codes and the corresponding node labels of a 4-D hypercube. Draw the mapping of the 16-node linear array on a 4-D hypercube.

b) p0 update x into 1
c) p1 read x

program translation/compilers
Use tombstone notation. If any code needs to be implemented, show what and also explain how - from scratch, or how, with minimal efforts unless stated otherwise.
1. You have machine M, and binaries for a C->M host compiler. You also have C source for Pascal->C translator. Show what you have with tombstone diagrams
2. You write an application PrjC in C. Show generative execution.
3. Redo showing interpretive execution..
4. You then write the same application in Pascal as PrjP. Show all that is needed for execution.
5. After doing the above, you need to run both projects on small N. Assuming that N is too small to run any translators, what you do? Show with diagrams.
6.If you can run compilers on N, and you want to implement one rather than buy, what you do? Show all steps with diagrams.

Sand and Surf Retailers recently acquired several smaller companies to expand its chain of clothing outlets. To establish consistency for the current organization and future acquisitions, Sand and Surf decided to develop an in-house application called SPS (Standard Purchasing System). The SPS system would standardize purchasing practices for each Sand and Surf subsidiary and manage all purchasing information. System testing will be completed by the end of the week.
