Pseudo RNG in Assembly

This is an exercise for writing a program in assembly, particularly using the ARM language, a Reduced Instruction Set Computing (RISC) Instruction Set Architecture (ISA). It generates a Pseudo Random Number computed using a specific sequence function, from two positive integer inputs, particularly a sequence length N and an initial value X.
