Solution

The correct implementation of the code is:

1sentence = input() 2space = ' ' # there is a single space between the quotes 3num_words = sentence.count(space) + 1 4print(num_words)

This code works by taking a sentence as input from the user. It then counts the number of spaces in the sentence and adds 1 to get the total number of words. This is because the number of words in a sentence is always one more than the number of spaces, assuming words are separated by a single space.

Raghu's tutor provides him a simple sentence and asks him to count the number of words in the sentence. The words are separated by space.Example, if the tutor provides the sentence as "Welcome to Java", the output should beNumber of words 3The words are WelcometoJavaFill the space in the below code so that the code fulfills his requirement. Code :                Scanner sc=new Scanner(System.in); String str=sc.nextLine(); String words[ ]  =   ; int count=  ;  //count holds the number of words in the sentence System.out.println("Number of words "+); System.out.println("The words are "); for(String    :     ) //for each loop System.out.println(x);

In the first line of input, accept a sequence of space-separated words. In the second line of input, accept a single word. If this word is not present in the sequence, print NO. If this word is present in the sequence, then print YES and in the next line of the output, print the number of times the word appears in the sequence.words = input().split('')test = input()if test not in words:    Print('No')else:    Print('YES')    count = 0    for word in words:        if test == word:            count -= 1                    Print(count)Sample Test CasesDownload All Test Case 1InputExpected OutputActual Outputa good collection of wordstheNOTest Case 2InputExpected OutputActual Outputno sentence can begin with because because because is a conjunctionbecauseYES3
