Is it a concern? count ['e'] = 4 count ['g'] = 2 count ['k'] = 2 Print all the indexes from the constructed array which have values greater than 1. 3) Now create a dictionary using Counter method having strings as keys and their frequencies as values. We use a list comprehension to iterate over the elements of the input list and include them in the list comprehension's result if their count in the input list is greater than 1 (i.e., they are duplicates). Let us look at the sample input and output of the program. Step 4 - Declare another result list to store the words after replacement.

The find () method is almost the same as the index () method, the only difference is that the index () method raises an exception if the value is not found.
Program to find the duplicate words in a string - Javatpoint To avoid case sensitivity, change the string to lowercase.3. 592), How the Python team is adapting the language for an AI future (Ep. The maximum depth of the call stack is equal to the number of words in the input sentence, so the space complexity is O(n). Additionally, we are creating a list to store the words in the output, which also takes O(n) space. For example: "Tigers (plural) are a wild animal (singular)". The reduce() function takes O(n) time to execute where n is the number of words in the input string. If the count of none of the words is greater than 1 then that is we are outside our loop then return No word is being repeated. If the first word is present in the rest of the words, call the function recursively with the rest of the words. Share your suggestions to enhance the article. This takes O(n) time where n is the length of the output string. Approach is very simple. To learn more, see our tips on writing great answers.
python - Why do I get "TypeError: Missing 1 required positional Time Complexity: O(N)Auxiliary Space: O(N), Time Complexity: O(N*N)Auxiliary Space: O(N). It only takes a minute to sign up.

You will be notified via email once the article is available for improvement. In the worst case, when there are no duplicates in the input string, the size of the output list is equal to the size of the input list, so the space complexity is O(n). Therefore, the time complexity of the function is O(n^2) because it has to perform this check for each word in the input string. Making statements based on opinion; back them up with references or personal experience. This is because we are using recursion to call the function with smaller subsets of the input sentence, which results in a recursive call stack. I'd combine those two lines. Auxiliary Space: O(n) where n is the number of elements in the list test_list. Step 3- Get words of the string using split() and store in a list, Step 4- Declare another result list to store the words after replacement, Step 5- Use list comprehension for a shorter syntax for writing replacement code. 4) Join each words are unique to form single string. Once the loops are completed, it uses another loop to print the words of. Another Approach: The idea is to tokenize the string and store each word and its count in hashmap. No need for the 0, range(x) == range(0, x). The time complexity of the remove_duplicates() function is O(n^2) where n is the number of words in the input string. I dislike the structure of this code.

To solve this problem in Python we can follow these approaches: In this approach, we will separate the words and then will memorize the first occurrence in the set and check if the value has already occurred before or not. Method #1 : Using set() + split() + loop The combination of above methods can be used to perform this task. Contribute your expertise and make a difference in the GeeksforGeeks portal. ; The for loop iterates through the lines in the list and gets the words in each line by using split(). Step 1: Get duplicate elements in a list with a frequency count Suppose we have a list of strings i.e. What its like to be on the Python Steering Council (Ep. We need to do this for each element in the list, so the overall time complexity is O(n * m * log(m)).
