Your program must contain at least two functions - the main function
for input and output and the second function for solving the problem.
Write a program that
(0) reads a set of
floating-point data values from the input, and
prints out the average (mean) of the data (see Exercise 4.24).
(1) reads a set of strings
and prints out the shortest of
(2) reads two natural numbers and prints out its greatest common
(3) reads two natural numbers and prints out its
least common multiple*.
(4) reads two strings and prints out true, if the second string is a
substring of the first and false,
(5) reads a positive number and prints out all its divisors.
(6) reads a positive number n
and prints out all prime numbers, less than n.
(7) reads a set of words
and prints them out in reverse order of their letters
(for example "print" as "tnirp").
(8) reads a set of
positive numbers and prints out their binary representations.
(9) reads a set of
positive numbers and prints out their octal
(10) reads a set of
strings of ones and zeros and prints out the numbers (in decimal
binary system* representations
are these strings.
(11) reads a positive integer N
and prints the sum of this number and the number generated by the
digits of N in backward
(12) reads a natural number n and prints out the
1 + 2.3 + 3.4.5 + 220.127.116.11 +...+ n.(n + 1)...(2n - 1).
(13) reads a natural number n and prints out the
sum of the prime divisors of n.
(14) reads a word and prints out "YES",
if it a palindrome*, i.e. a
word, that reads the same backward or
(15) reads two words and prints out "YES", if the second
word is made by transposing the letters of the first word (anagram*).
(16) reads a string and prints out all repeating (at least twice)
symbols in it.
(17) reads two positive integers a
and b (a < b) and prints out the count
of integer numbers in the interval [a,b],
which have no the same digits (example: 120,123,124,125 in the interval
(18) reads a positive number n
and prints out first n
numbers (from the sequence 1,2,3,4,5,...) which are divisible* by
2, 3 and 5.
(19) reads two natural numbers a
and b and prints
out the number of digits of ab
(the product of a
(20) reads a positive number n
and prints out a list of all perfect
numbers* (are equal to
the sum of all of their factors*),
less than n.
The phrase "reads
a set of" means processing a sequence of inputs, 4.6 from Chapter
