	Sentence 1 at line 2: Why need one program?

+++ Paragraph 2 begins at line 4
	Sentence 2 at line 4: The electronic speed possessed by computers for processing data >>
		>> is really fabulous.
	Sentence 3 at line 5: Can you imagine a human prodigy manually multiplying >>
		>> two thousand digit integers flawlessly in an hour?
	Sentence 4 at line 6: A computer can perform >>
		>> that multiplication so fast that you even do not perceive that it has >>
		>> taken any time at all.
	Sentence 5 at line 8: It is wise to exploit this instrument to the best >>
		>> of our benefit.
	Sentence 6 at line 9: Why not, right?

+++ Paragraph 3 begins at line 11
	Sentence 7 at line 11: However, there are many programs already written by professionals >>
		>> and amateurs.
	Sentence 8 at line 12: Why need we bother about writing programs ourselves?
	Sentence 9 at line 13: If we have to find the roots of a polynomial or invert/multiply matrices >>
		>> or check primality of natural numbers, we can use standard mathematical >>
		>> packages and libraries.
	Sentence 10 at line 15: If we want to do web browsing, it is not a >>
		>> practical strategy that everyone writes his/her own browser.
	Sentence 11 at line 17: It is reported that playing chess with the computer could be a really >>
		>> exciting experience, even to world champions like Kasparov.
	Sentence 12 at line 18: Why should >>
		>> we write our own chess programs then?
	Sentence 13 at line 19: Thanks to the free (and open-source)  >>
		>> software movement, many useful programs are now available in the >>
		>> public domain (often free of cost).

+++ Paragraph 4 begins at line 23
	Sentence 14 at line 23: Still, we have to write programs ourselves!
	Sentence 15 at line 23: Here are some >>
		>> compelling reasons.

+++ Paragraph 5 begins at line 27
	Sentence 16 at line 27: * There are so many problems to solve >>
	*** Paragraph ended before sentence finishes

+++ Paragraph 6 begins at line 29
	Sentence 17 at line 29: Simple counting arguments suggest that computers can solve >>
		>> infinitely many problems.
	Sentence 18 at line 30: Given that the age of the universe and the >>
		>> human population are finite, we cannot expect every problem to be >>
		>> solved by others.
	Sentence 19 at line 32: In other words, each of us is expected to encounter >>
		>> problems which are so private that nobody else has even bothered to >>
		>> solve them, let alone making the source-codes or executables freely >>
		>> available for our consumption.
	Sentence 20 at line 35: Sometimes programs are available for >>
		>> solving some of our problems, but these programs are either too costly >>
		>> to satisfy our budget or so privately solved by others that they don't >>
		>> want to share their programs with us.
	Sentence 21 at line 38: If we plan to harness the >>
		>> electronic speed of computers, there seems to be no alternative way >>
		>> other than writing the programs ourselves.

+++ Paragraph 7 begins at line 42
	Sentence 22 at line 42: A stupendous example is provided by the proof of the four-color >>
		>> conjecture, a curious mathematical problem that states that, given the >>
		>> map of any country, one can always color the states of the country >>
		>> using only four colors in such a way that no two states that share >>
		>> some boundary receive the same color.
	Sentence 23 at line 46: That five colors are sufficient >>
		>> was known since long ago, but the four-color conjecture remained unsolved >>
		>> for quite a long time.
	Sentence 24 at line 48: Mathematicians reduced the problem to checking >>
		>> a list of configurations.
	Sentence 25 at line 49: But the list was so huge that nobody could >>
		>> even think of hand-calculating for all these instances.
	Sentence 26 at line 50: A computer >>
		>> program helped them explore all these possibilities.
	Sentence 27 at line 51: The four-color >>
		>> conjecture finally came out to be true.
	Sentence 28 at line 52: Conservatives raised a huge >>
		>> hue and cry about such filthy methods of mathematical problem solving.
	Sentence 29 at line 54: But a problem solved happens to be a problem solved.
	Sentence 30 at line 54: Let them cry!

+++ Paragraph 8 begins at line 56
	Sentence 31 at line 56: Computers can aid you solving many problems of various flavors >>
		>> ranging from mundane to practical to esoteric to deeply theoretical.
	Sentence 32 at line 58: Moreover, anybody can benefit from programming computers, >>
		>> irrespective of his/her area of study.
	Sentence 33 at line 59: It's just your own sweet will >>
		>> whether you plan to exploit this powerful servant.

+++ Paragraph 9 begins at line 63
	Sentence 34 at line 63: * Hey, we can write better programs than them >>
	*** Paragraph ended before sentence finishes

+++ Paragraph 10 begins at line 65
	Sentence 35 at line 65: Yes, we often can.
	Sentence 36 at line 65: Available programs may be too general, and >>
		>> we can solve instances of our interest by specific programs much more >>
		>> efficiently than the general jack-of-all-trades stuff.
	Sentence 37 at line 67: Moreover, >>
		>> you may occasionally come up with brand-new algorithms that hold >>
		>> the promise of outperforming all previously known algorithms.
	Sentence 38 at line 70: You would then desire to program your algorithms to see how they >>
		>> perform in reality.
	Sentence 39 at line 71: Designing algorithms is (usually) a more difficult >>
		>> task than programming the algorithms, but the two may often go >>
		>> hand-in-hand before you jump to a practical conclusion.
