Write a program that reads an input.txt file and generates a word frequency chart. HINT: Use a dictionary where the words read from the file are keys, and each key has an associated count. Be sure to use strip and lower to ensure your check is case insensitive, and also not sensitive to trailing or leading whitespace characters. For instance, if given the file found in input-1.txt & , the output would look as follows: this : * * the : * * *# today : * * tomorrow: holiday : class : classroom: * sunday : * good : * bad : hello: * * world : * * program
