  1. Some Programming Examples

  2. Complete number In mathematics, a perfect number is defined as a positive integer which is the sum of its proper positive divisors, that is, the sum of the positive divisors excluding the number itself E.g., 6=1+2+3

  3. Complete number for j in range(2,1001): k = [] n = -1 s = j for i in range(1,j): if j % i == 0: n += 1 s -= i k.append(i) if s == 0: print j

  4. Narcissistic number In number theory, a narcissistic number or pluperfect digital invariant (PPDI) or Armstrong number is a number that in a given base is the sum of its own digits to the power of the number of digits E.g., 153= 1**3+5**3+3**3

  5. Narcissistic number for n in range(100,1001): i = n / 100 j = n / 10 % 10 k = n % 10 if i * 100 + j * 10 + k == i + j ** 2 + k ** 3: print "%-5d" % n

  6. Monkey eats peaches A little monkey had some peaches. On the first day he decided to keep 1/2 of his peaches. He gave the rest away.Then he ate one. On the second day he decided to keep 1/2 of his peaches. He gave the rest away. Then he ate one. On the third day he decided to keep 1/2 of his peaches. He gave the rest away. Then he ate one. On the tenth day he found he had only one left. How many did he have at the beginning?
