• (examples in Python unless otherwise noted)
  • a series of steps that can be followed to solve a problem
  • examples:
    • palindrome - same forwards and backwards
      • reverse order of string, make both all lower or upper, remove any punctuation, and see if two strings match
    • FizzBuzz - print list of numbers, but sub 'Fizz' for multiples of 3, 'Buzz' for multiples of 5, and 'FizzBuzz' for multiples of 3 and 5
      • use modulo % with conditionals
    • anagram - two words with all the same letters
      • match their cases,sort both words alphabetically, then see if match
      • Python has a built in function sorted() that will alphabetize for you
    • count number of times each character occurs in a string
      • def count_characters(string):
          count_dict = {}
          for c in string:
          if c in count_dict:
              count_dict[c] += 1
              count_dict[c] = 1
        • each key will be a character and each value will be the number of times it occurred in the string
