Write a python program that can tell if two strings are anagrams with each other. Anagrams are strings can be formed from one another by rearranging the letters. We only consider letters a-z A-Z and digits 0-9 in our strings and ignore all other characters (spaces, punctuation marks and so on.) and we ignore cases of letters (e.g. a and A are considered the same) for comparison.  Your program must define is_anagram(s1, s2) function that returns True when s1 and s2 are anagrams and returns False when they are not.

Computer Science Write a Java program that reads a line and a line segment and then determines whether they intersect or not. When they overlap completely, consider that as intersecting. Use variables ((lp1x, lp1y), (lp2x, lp2y)) to represent a line and ((sp1x, sp1y), (sp2x, sp2y)) to represent a line segment

Write a program that will read a line of text and output the number of words in the line and the number of occurrences of each letter. Define a word to be any string of letters that is delimited at each end by either whitespace, a period, a comma, or the beginning or end of the line. You can assume that the input consists entirely of letters, whitespace, commas, and periods. When outputting the number of letters that occur in a line, be sure to count uppercase and lowercase versions of a letter as the same letter. Output the letters in alphabetical order and list only those letters that occur in the input line. For example, the input line I say Hi. should produce output similar to the following: 3 words 1 a 1 h 2 i 1 s 1 y

Write a program that reads a list of words. Then, the program outputs those words and their frequencies (case insensitive). Ex: If the input is: hey Hi Mark hi mark the output is: hey 1 Hi 2 Mark 2 hi 2 mark 2 Hint: Use lower() to set each word to lowercase before comparing. In Python Please.
