String Game ALL Write a program that would take a string from STDIN and print to STDOUT number of unique" words present in the string (26 pts). The input read from STDIN will be a single line of text that can potentially contain letters, numbers, symbols, and spaces, but will not contain any newline characters. Each word in the input is separated by a comma. • Ignore any Cases ie. "Upper" and "upper" should be considered one • Any non-alphanumerics shouldn't be ignored i.e. Dr's and Drs should be considered as different strings • Make sure you are looking at Unique Strings only fie. if Dr's is repeated twice, it should be counted only once) Running your program with no custom test cases will test it against the test cases your submission will be evaluated on. The basic test cases have visible output and targets so you can see where your program deviates from the desired result, while the more challenging cases are hidden There are runtime limits on each case as well, so if your submission is not algorithmically efficient, you may see that some of the larger Cases time out. It is not required to pass all the test cases to pass the question, but you should attempt to make as many as possible pass. Client Assignment player ES Type here to search

Answer 1

Python makes the work a lot easier.

Code:

#taking input from the user
my_input = input("Enter the string:")

# converting the string to upper case so that
# the string is non case-sensitive'''
my_input = my_input.upper()

#seperating the words in a list
words_list = my_input.split()

#convert the list to set
#as set contains only unique elements
myset = set(words_list)

#Display no. of unique words
print ("There are" , len(myset), "unique words in the string.")

Screenshots:

i #taking input from the user 2 my_input = input("Enter the string:") 4 5 # converting the string to upper case so that # the string is non case-sensitive' my_input = my_input.upper() 8 #seperating the words in a list 9 words_list = my_input.split() 10 #convert the list to set #as set contains only unique elements 13 myset = set(words_list) 15 16 17 #Display no. of unique words print ("There are" , len(myset), "unique words in the string.") input Enter the string: London LONDon Mrs Mr's Melbourne There are 4 unique words in the string.
