BinarySearch: int binary_search(MountainArray &mountain, int target, int l, int r, int key(int)) { std::cout<<"target="<<target<<std::endl; target = key(target); std::cout<<"key target="<<target<<std::endl;

    while (l <= r) {
        int mid = (l + r) / 2;
        int cur = key(mountain.get(mid));
        if (cur == target)
            return mid;
        else if (cur < target)
            l = mid + 1;
        else
