Write a function in Scala programming language that takes a string parameter and returns whether the string starts with "Sc" or not. Test the function for the sample strings "Scala", "Proqramming","Science".

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 <iostream>#include <string>#include <cctype>using namespace std; /* Your code goes here */ int main() {   string input;   string output;    getline(cin, input);        output = RemoveCommas(input);      cout << output << endl;    return 0;}

Write a python program and add a function named words_and_sents() to it. Thisfunction takes a string parameter called text. Your function should count and print thetotal number of words and sentences in the text. Assume that every word in the text is asubstring followed by a space character “ “. Also, assume that every sentence in the textis a string containing one or more words and must end with a “.” or “?” character. Finally,capitalize each sentence (i.e., convert the first letter to uppercase) and print them onseparate lines. See the sample output below.>>> text = "hello, here are some words. and some sentences. canyou count them.">>> words_and_sents(text)#sentences = 3, #words = 12Printing sentences:Hello, here are some words.And some sentences.Can you count them.

Write a function called reverse that takes a parameter N which is a string and returns the reverse of the string.

python help... Write a function justVowels() that takes a string as a parameter and returns a new string that contains all the vowels found in the parameter string. The vowels in the returned string should appear in the same order as they did in the parameter string. A vowel is one of a, e, i, o, or u. both the upper- and lower-case vowels should be included. The characters in the returned string should have the same capitalization as they did in the parameter string. If the function is given a string without any vowels or an empty string, it should return the empty string. Use the if-else condition with iterate loop pattern. Don’t forget to include the docstring and comments.    How it should run... >>> justVowels('Did you include your collaboration statement') 'iouiueouoaoaioaee' >>> justVowels('If you did not include your collaboration statement no points') 'Iouioiueouoaoaioaeeooi' >>> justVowels('1,2,3,4,...') '' >>> justVowels('') ''
