1. Write two C++ literals for Kelvin and Fahrenheit conversions to Celsius so that the following code works.

int main() {
    float a = 300_Kelvin;
    float b = 120_Fahrenheit;
    return 0;
}

2. Implement a class template for a Vector of elements that has the following methods:

• insert(index, element): inserts the element at the specified index (must be between 0 and size)
• remove(index): removes an element at the specified index
• sort(cmp): sorts the vector by using a comparison function; add an overload that takes no parameters and uses operator< instead
• print: prints the vector elements

The vector should also have a copy/move constructor, along with an operator[] defined, which returns the element at the given index. You MUST have the implementation in the header.

int compare_ints(int x, int y) {
    // return -1, x < y
    // return 1, x > y
    // return 0, x == y
}

int main() {
    Vector<int> v;

    // index, element
    v.insert(0, 10);
    v.insert(1, 5);
    v.insert(2, 20);

    Vector<int> w = v;

    // index
    v.remove(0);
    v.sort(compare_ints);
    printf("%d\n", w[0]);

    v.print();
}
