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),…
- 1. What type of strings are accepted following Res? a. (a|b)* b. (ab)* c. (a+b)*b(a+b)* d. aa(a+b)* e. aa(a+b)*bbmergeAndRemove(int[], int[]) This is a public static function that takes a int[] and int[] for the parameters and returns an int[]. Given two arrays of integers. Your job is to combine them into a single array and remove any duplicates, finally return the merged array.In c++ Write a for loop to print all elements in courseGrades, following each element with a space (including the last). Print forwards, th backwards End each loop with a newline. Ex If courseGrades (7, 9, 11, 10), print: 7 9 11 10 10 11 9 7 Hint Use two for loops. Second loop starts with i=NUM VALS-1. (Notes) Note: These activities may test code with different test values. This activity will perform two tests, both with a 4-element array (int courseGrades(4) See 'How to Use zyBooks Also note: If the submitted code tries to access an invalid array element, such as courseGrades[9] for a 4-element array, the test may generate strange results. Or the test may crash and report "Program end never reached", in which case the system doesn't print the test case that caused the reported message 32344345730rity? 2 using namespace std; 3 4 int main() { 5 6 7 8 9 10 11 12 13 14 const int NUM VALS-4; int courseGrades [NUM VALS]; int i; for (i = 0; i > courseGrades[1]; } y Your solution goes here Y

However, to make the result look prettier, the capitalization of each moved vowel must be the same as that of the vowel that was originally in the target position. For example, reversing the vowels of 'Ilkka' should produce 'Alkki' instead of 'alkkI'. Applying this operation to random English sentences seems to occasionally give them a curious pseudo-Mediterranean vibe.Along with many possible other ways to perform this square dance, one straightforward way to reverse the vowels starts with collecting all vowels of text into a separate list, and initializing the result to an empty string. After that, iterate through all positions of the original text.…CodeW For fun X C Solved https://codeworkou... 臺亂 CodeWorkout X272: Recursion Programming Exercise: Is Reverse For function isReverse, write the two missing base case conditions.
