Write a function (named "Lookup") that takes two const references to vectors. The first vector is a vector of strings. This vector is a list of words. The second parameter is a list of ints. Where each int denotes an index in the first vector. The function should return a string formed by concatenated the words (separated by a space) of the first vector in the order denoted by the second vector.

Input of Test Case provided in PDF:

 

#include <string>
#include <vector>
#include <iostream>
const std:vector<std::string> words {"zero", "one", "two"};
const std:vector<int> indices {2, 1, 1, 2, 0};
std::string result = Lookup(words, indices);
std::cout « result « std::endl;
const std::string expected = "two one one two zero ";
ASSERT_EQ(expected, result);
