Problem Statement:
We are given a sentence, we need to find all possible combinations of two words and print them in lexicographical order. Ignore all adjacent combinations and print the rest combinations only.
Code to find Two words combination in Python:
sentence = input('Enter sentence: ')
sentence = sentence.split(' ')
all_comb = []
for i in range(len(sentence)-2):
for j in range(i+2, len(sentence)):
all_comb.append([sentence[i], sentence[j]])
all_comb = sorted(all_comb, key=lambda x: (x[0]))
for i in range(len(all_comb)):
for j in range(2):
for k in range(1, len(sentence)-1):
try:
if all_comb[i][j]==sentence[k]:
try:
if all_comb[i][j+1]==sentence[k+1]:
all_comb.pop(k)
except:
a=1
try:
if all_comb[i][j+1]==sentence[k-1]:
all_comb.pop(k)
except:
a=1
try:
if all_comb[i][j-1]==sentence[k+1]:
all_comb.pop(k)
except:
a=1
try:
if all_comb[i][j-1]==sentence[k-1]:
all_comb.pop(k)
except:
a=1
except:
a=1
print(all_comb)Output:
