Given an unordered_set names, compare the code segments if (names.count("Fred") and == } 1) { cout << "found" << endl; } for (auto iter = names.begin(); iter != names.end(); iter++) { if (*iter == "Fred") { cout << "found" << endl; } Which statement about these code segments is true? O They have the same result, but the first one is more efficient. O They have the same result, but the second one is more efficient. They have the same efficiency when "Fred" is at the end of the set and different results when it is near the front. O They have the same result and both are equally efficient.

Data Structures and Algorithms in C/C++ In this assignment, you will be using quicksort to sort an array of car objects by various criteria Define a struct Car as follow: #define MAX_STRING_LENGTH typedef struct Car_ { char make[MAX_STRING_LENGTH]; char model[MAX_STRING_LENGTH]; int mpg; /* Miles per gallon */ } Car; Implement a function called compareCarsByMakeThenModel that can be passed as an argument to the compare parameter of the qksort function from the book. compareCarsByMakeThenModel should return a value that will cause qksort to sort an array of cars in ascending order (from smallest to largest) by make and, when two cars have the same make, in ascending order by model. Implement a function called compareCarsByDescendingMPG that can be passed as an argument to the compare parameter of the qksort function from the book. compareCarsByDescendingMPG should return a value that will cause qksort to sort an array of cars in descending order (from largest to smallest)…
