Data structure & Algorithum. Java Program Write code that accomplishes the following tasks. Consider two bags that can hold strings. One bag is named letters and contain seeral one-letter strings. The other bag is empty and is namedvowels. One at a time removed a string from letters. If the string contain a vowel place it into bag vowels, otherwise, discard the string. After you have checked all of the strings in letters, report the number of vowels and the number of times each vowels appears in the bag.

note: You can easily replace a portion of text within a String using the String method "replace()". For example: String svar = "raspberry jam"; svar = svar.replace("jam", "pie"); System.out.println(svar); will print out: raspberry pie A photographer is organizing a photo collection about the national parks in the US and would like to annotate the information about each of the photos into a separate set of files. Write a program that reads the name of a text file containing a list of photo file names. The program then reads the photo file names from the text file, replaces the "_photo.jpg" portion of the file names with "_info.txt", and outputs the modified file names. Assume the unchanged portion of the photo file names contains only letters and numbers, and the text file stores one photo file name per line. If the text file is empty, the program produces no output.

Word Statistics: The second requirement change is to allow replacement of all occurrences of a given word to a given replacemWrite the code only in python language with the opeartion exactly and necessary comments to be added.

Using phyton code:  First, ask the user the following three questions and store the answers in a nested list.  What is your name? What is your quest? What is your favorite color? Store at least 6 sets of responses. Example nested list: [ ['Sir Robin' , 'to find the Holy Grail' , 'red'] , ['Matt' , 'to travel the world' , 'blue'], etc...] Second, sort the list alphabetically by color and print out the results: Sample output:

Add a while loop to the BMI prcoedure below.     def BMIImperial(height, weight, bmiList, Category): BMI = (weight * 703) / (height * height)print ("Your BMI is " + str(BMI))if (BMI <= bmiList[0]):print(BMI)print('you are:', Category[0])elif (BMI <= bmiList[1]):print('you are:', Category[1])elif (BMI <= bmiList[2]):print('you are:', Category[2])else:print('you are:', Category[3])

public static String[] getTokens(String raw, String delimiter){ // Line #1 goes here... int numTokens = st.countTokens(); // Line #3 goes here... for(int i = 0; i < numTokens; i++){ // Line #5 goes here } // Line #7 goes here } Using the code above, which one of these should be the code for "Line #7": ret[i] = st.nextToken(); return ret; String[] ret = new String[numTokens]; StringTokenizer st = new StringTokenizer(raw, delimiter);

Please help. This is Python I feel so lost

Counting hashtags Write Python code to count the frequency of hashtags in a twitter feed. Your code assumes a twitter feed variable tweets exists, which is a list of strings containing tweets. Each element of this list is a single tweet, stored as a string. For example, tweets may look like: tweets = ["Happy #IlliniFriday!", "It is a pretty campus, isn't it, #illini?", "Diving into the last weekend of winter break like... #ILLINI #JoinTheFight", "Are you wearing your Orange and Blue today, #Illini Nation?"]   Your code should produce a sorted list of tuples stored in hashtag_counts, where each tuple looks like (hashtag, count), hashtag is a string and count is an integer. The list should be sorted by count in descending order, and if there are hashtags with identical counts, these should be sorted alphabetically, in ascending order, by hashtag. From the above example, our unsorted hashtag_counts might look like: [('#illini', 2), ('#jointhefight', 1),…
