8. Write a function called string_reverse() that accepts a string from the user as a parameter. The function should create and return a new string that contains all the same letters of the parameter string, but in reverse order. For Cedarbrae C.I. ICS3U example, string_reverse("Hello World") would return "dirolW olleW". Write a main () function to demonstrate how it works.

code should be python: write a function that allows the input of a list of strings as its only parameter. Inside the body of the function find the first palindromic word and return it. If there is no such word, it should return an empty string. A string is palindromic if it reads the same forward and backward so for example If we call the function with [“horse”, “rat”, “roar”, “dad”, “mom”], the returned value should be “dad”. Note that “mom” is also a palindrome, but it is not the first one.

Assume that the first listed element is the representative for each set in a disjoint-set. Show the data structure of the disjoint set S: {{0, 1, 2}, {3, 5}} as it is being built using a linked list representation.

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 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", "Programming", "Science".

Write a function that counts the occurrences of a word in a string. Thefunction should return an integer. Do not assume that just one space separates words and a string can contain punctuation. Write the function sothat it works with either a String argument or a StringBuilder object

Complete the rotate_text() function that takes 2 parameters, a string data and an integer n. If n is positive, then the function will shift all the characters in data forward by n positions, with characters at the end of the string being moved to the start of the string. If n is 0 then the text remains the same. For example: rotate_text('abcde', rotate_text('abcde', rotate_text('abcde', 1) would return the string 'eabcd' 3) would return the string 'cdeab' 5) would return the string 'abcde' rotate_text('abcde', 6) would return the string 'eabcd' ... and so on. If n is negative, then the function will shift the characters in data backward by n positions, with characters at the start of the string being moved to the end of the string. For example: rotate text('abcde', -1) would return the string 'bcdea'

Write a function called translate_to_italian () that takes a string as a parameter (a colour). translates the colour into the Italian word and returns the translated text (as a string). Your function should translate the following colours into their Italian equivalent: ● Green= Verde • Purple E Viola Pink Rosa . Silver Argento . If a colour is passed to the function that is not contained in the above list, the function should return the string "I don't understand?". For example: Calling the function translate_to_italian like so: translation translate_to_italian ("Pink") will assign to the string "Rosa" to variable translation. - Calling the function translate_to_italian like so: = translate_to_italian ("Red") translation

Write a program that removes all spaces from the given input. Ex: If the input is: Hello my name is John. the output is: HellomynameisJohn. Your program must define and call the following function. The function should return a string representing the input string without spaces.string RemoveSpaces(string userString) #include <iostream>#include <algorithm>using namespace std; string removeSpaces(string str) { str.erase(remove(str.begin(), str.end(), ' '), str.end()); return str; } /* Define your function here */ int main() {string str; str = removeSpaces(str); cout << str << endl; /* Type your code here. Your code must call the function. */ return 0;} Please help me with this problem using c++.
