Q: Here’s something to stop you from getting repetitive when writing essays. Write a program that reads multiple lines of plain text from the user, then prints out each different word in the input with a count of how many times that word occurs. Don’t worry about punctuation or case – the input will just be words, all in lower case. Your output should list the words in alphabetical order. For example: Enter line : which witch Enter line : is which Enter line : is 1 which 2 witch 1 A??: dic_line1 = { } dic_line2 = { } list = [ ] enter_line = input ( "Enter line: " ) . lower ( ) while enter_line

1014 Waiting in Line (30分) Suppose a bank has N windows open for service. There is a yellow line in front of the windows which devides the waiting area into two parts. The rules for the customers to wait in line are: The space inside the yellow line in front of each window is enough to contain a line with M customers. Hence when all the N lines are full, all the customers after (and including) the (NM+1)st one will have to wait in a line behind the yellow line. Each customer will choose the shortest line to wait in when crossing the yellow line. If there are two or more lines with the same
