Confucius_grammar Challenge Solution

for arg in ARGV
   file = File.open(arg)

   file_data = file.read

   file_data.each_line do |line|
     puts line.downcase.sub(/^./, &:upcase).gsub(" i "," I ").sub(" he "," He ")
   end
end

Solution Notes:

The .downcase method converts all alphabetical strings into lower case characters. The .sub(/^./, &:upcase) method takes beginning characters of each line and then converts them into uppercase characters. The .gsub(“ i “,” I “) method globally convert all “i” into “I” characters for grammatical correctness. The .sub(“ he “,” He “) method converts all “he” into “He” for grammatical correctness.
