Answer 1

#get the input sentence from the user
sentence = input("Enter a sentence: ")

#split the sentence into separate words
s = sentence.split()

#sort the words in alphabetical order
s.sort()

#initialize a list to store the paired words
result = []

n=len(s) #get the length of the splitted sentence

for i in range(n):
    for j in range(i+1,n):
        two_words=s[i]+" "+s[j]
        result.append(two_words)  #append the words to the list

#display each line containing the unique combination of two words in lexicographical orde
for item in result:
    print(item)
