Define a function RemoveCommas() that takes a string parameter and returns a string. The returned string is the parameter with all of the commas removed. Ex: RemoveCommas("mouse,toy,fox,bear,pet") returns "mousetoyfoxbearpet" Recall string's size() returns the number of characters in a string. Ex: myString.size() string's at() returns a character at the specified position in the string. Ex: myString.at(3)   #include #include #include using namespace std; /* Your code goes here */ int main() {    string input;    string output;    getline(cin, input);         output = RemoveCommas(input);        cout << output << endl;    return 0; }

palindromes Write a function palindromes that accepts a sentence as an argument. The function then returns a list of all words in the sentence that are palindromes, that is they are the same forwards and backwards. Guidelines: • punctuation characters .,;!? should be ignored • the palindrome check should not depend on case Sample usage: >>> palindromes ("Hey Anna, would you prefer to ride in a kayak or a racecar?") ['Anna', 'a', 'kayak', 'a', 'racecar'] >>> palindromes ("Able was I ere I saw Elba.") ['I', 'ere', 'I'] >>> palindromes ("Otto, go see Tacocat at the Civic Center, their guitar solos are Wow!") ['Otto', 'Tacocat', 'Civic', 'solos', 'wow'] >>> palindromes ("Otto, go see Tacocat at the Civic Center, their guitar solos are wow!")==['Otto', 'Tacocat', 'Civic', 'solos', 'wow'] True

Scala Programming: Given string str, write a Scala program to create a new string where "Scala " is added to the front of a given string. If the string already begins with "Scala", return the string unchanged. Otherwise, return the string after adding "Scala ". Test the function for two strings "Scala Programming" and "Programming" inside the main method.

C++ Add a search command that asks the user for a string and finds the first line that contains that string. The search starts at the first line currently displayed and stops at the end of the file. If the string is found, the line that contains it is displayed at the top. In case the user enters a string X that does not occur in the file, the program should print the error message: ERROR: string "X" was not found.  Attached is the first lines of the .txt file

python programing：  You are going to create a race class, and inside that class it has a list of entrants to the race.   You are going to create the daily schedule of three or so races and populate the races with the jockey/horse entries and then print out the schedule.   Create a race class that has   The name of the race as a character string, ie “RACE 1” or “RACE 2”,  The time of the race A list of entries for that race   Create a list of of 3 (or 4) of those race objects(races) for the day   For the list of entries for a particular race, make a entrant class (the building block of your entrants list) you should have   The horse name The jockey name   Now you need to   Populate the structure (ie set up three races on the schedule, add 2-3 horses entries to each race.  You can hardcode the entries if you want to, rather than getting them from the user, just to save the time of making a menu interface and whatnot. Be able to print the days schedule   So example output would be…
