8. Experience indicates that the average programmer produces N lines of documented, debugged code per day, on the average, for which N is some number less than 10. High-level code is typically n1 times as efficient as assembly code (i.e., a given job requires 1/n1 times as many lines of code as lower level code) and Prolog is typically n2 times as efficient as high-level language where n1 and n2 are in the range 4 to 10. Find evidence supporting these numbers and interpret your results in terms of the implications of NLP for programming productivity.
