Write a function, isPalindrome, that returns true if a string is a palindrome and false otherwise. A string is a palindrome if it reads forward and backward in the same way. For example, the strings "madamimadam", "5", "434", and "789656987" are all palindromes. The prototype of the function is as follows:  bool isPalindrome(string str);

Write a function that when given a URL as a string, parses out just the domain name and returns it as a string. Examples:domain_name("http://github.com/SaadBenn") == "github" domain_name("http://www.zombie-bites.com") == "zombie-bites"domain_name("https://www.cnet.com") == "cnet"Note: The idea is not to use any built-in libraries such as re (regular expression) or urlparse except .split() built-in function""" # Non pythonic waydef domain_name_1(url):    #grab only the non http(s) part    full_domain_name = url.split('//')[-1]     #grab the actual one depending on the len of the list      actual_domain = full_domain_name.split('.')          # case when www is in the url    if (len(actual_domain) > 2):        return actual_domain[1]        # case when www is not in the url    return actual_domain[0] # pythonic one linerdef domain_name_2(url):

How to write a function in python that takes a string s = kkeeepinng and returns the non-repeating character from strrint s. Such that the output should be as follows:  p i g

Define a function FilterStr() that takes a string parameter and returns "Acceptable" if the first character and the character at index 3 in the string parameter are the same. Otherwise, the function returns "Unacceptable". Ex: FilterStr("surfing") returns Unacceptable Recall 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 = FilterStr(input);   cout << output << endl;    return 0;}
