from std library c++11.
1) implement the function - void* aligned_alloc(size_t alignment , size_t size)
2) implement the function - aligned_free(void* ptr)
* you can use malloc() and free() from std library in your solution

part 1 sol:
void* alignment_alloc(size_t align, size_t size) {
	void* p1 = (void*)malloc(size + (align - 1));
	int res = (int)p1 % align;
	void* p2 = (void*)(align - res + (int)p1);
	return p2;
}

part 2 sol was explained without writing the code.
