It is entirely possible that two programmers could write very similar code to solve the same simple problem—say a program to play tic-tac-toe. however, as the problem being addressed grows in size and complexity, the number of ways to code a solution also grows. this can create a temptation for one programmer to “paraphrase” ideas taken from another programmer’s work, rather than writing original code. how might such “para- phrasing” be detected? should paraphrasing of another’s code be considered copyright or patent infringement? why or why not?
