Solve the following problem:
Realize a network for the code converter which converts the binary code with weights 4221 of first 10 non-negative integers numbers into the Gray code. Notice that a Gray code represents each number in the sequence {0, 1,... 2n} as a binary n-tuple such representations of adjacent numbers differ in a single bit. There may be many Gray codes for a given n. This often used is the binary-reflected Gray code which can be generated by starting from the n-tuple of all bits zero and successively flipping the right-most bit that produces a new sequence.
