9 >= 0 so return 9 + ...
8 >= 0 so return 8 + ...
7 >= 0 so return 7 + ...
6 >= 0 so return 6 + ...
5 >= 0 so return 5 + ...
4 >= 0 so return 4 + ...
3 >= 0 so return 3 + ...
2 >= 0 so return 2 + ...
1 >= 0 so return 1 + ...
0 >= 0 so return 0 + ...
-1 is not >= 0 so return 0.

Now string together all the returns..
9+8+7+6+5+4+3+2+1+0+0=45

recur(9) returns 45

Prior to the creation of the us constitution, the general view of representative government is that it only worked in very small-scale environments- essentially a city-state or smaller. otherwise, the actual reflection of popular will declined in the representatives (ie, the difference between 1 representative per 100 citizens and 1 representative per 10,000 citizens), and generally the whole process became inefficient and self-destructive.james madison, however, was like 'no beezy'. he remarked that small republics were prone to faction and thus collapsed quickly. a large republic, he said, had so many interests and factions that none could rule, and thus they had to moderate and compromise.

like many students at university, you may be unhappy about the results you attain in exams. you may feel that even with all you are doing there must be something more -- or different-- you could be doing to get better grades. we have all at some time or other heard of that student who only studies a couple of hours for final exams and scores a's every time. we stand in awe of those who seem to breeze through without undue effort and seem to need very little in the way of studying to nail an exam. the reasons for success, in what i think are the vast majority of cases, are less esoteric than many students think: successful students consistently apply a series of productive strategies with view to attaining clearly identified learning and grade goals throughout the academic term.
