The list of the Morse code for all English letters (from a to z) is provided below: [".-","-...","-.-.","-..",".","..-.","--.","....","..",".---","-.-",".-..","- -","-.","---",".--.","--.-",".-.","...","-","..-","...-",".--","-..-","-.-- ","--.."] Your goal here is to implement a function that takes a list of strings as its only parameter (called "words"). Each of the words can be transformed to Morse code by concatenation of a number of the above strings (without spaces). For example, the transformation of "ab" will be ".--..." (".-" + "-..."). The word "ems" will also have the same transformation ".--..." ("." + "--" + "..."). In this function, the goal is to return the number of the unique transformations in "words" list. Here is an example (none of this is needed to be printed, the function will only return one integer): Words = ["ab", "a", "ems"]Returned value: 2Explanation:...arrow_forward#include <iostream>#include <sstream>#include <string>using namespace std; int main() { string userItem; ostringstream itemsOSS; cout << "Enter items (type Exit to quit):" << endl; cin >> userItem; while (userItem != "Exit") { cin >> userItem; } cout << itemsOSS.str() << endl; return 0;}arrow_forward
