Answer:

The solution in Python is as follows:

str = "sample.txt"

a_file = open(str, "r")

words = []

for line in a_file:

stripped_line = line.strip()

eachlist = stripped_line.split()

words.append(eachlist)

a_file.close()

word_list= []

n = int(input("Number of words: "))

for i in range(n):

myword = input("Enter word: ")

word_list.append(myword)

for rn in range(len(word_list)):

index = 0; count = 0

print()

print(word_list[rn]+": ",end = " ")

for i in range(len(words)):

 for j in range(len(words[i])):

  index+=1

  if word_list[rn].lower() == words[i][j].lower():

   count += 1

   print(index-1,end =" ")

if count == 0:

 print("Word not found")
