Strings

Exercise 1 (Warmup)

Write a program that repeats a string n times.

Exercise 2 (Shuffle)

Write a program that prompts the user for a stirng. Print the stirng in reverse order

Example of output

  Enter string:

Exercise 3 (Palindromes)

Write a program that prompts the user for a string and checks (and prints) if it is a palindrome. That is "a word, phrase, or sequence that reads the same backward as forward". Example: madam or nurses run. Note that, as in the second example, spaces (and capitalization) should be ignored.

Example of output

  Enter string:
  > madam

madam is a palindrome

Exericse 4 (Word Frequencies)

Write a program which reads a string and prints the word frequency for each word.

Example of output

the seashells she sells are seashore shells

Word Frequencies:
sally 1
sells 3
seashells 3
by 1
the 3
