space complexity

例句：

1. 1. The algorithm's space complexity is O(n), which means it requires a constant amount of memory regardless of the size of the input data.
   该算法的空间复杂度为O(n)，意味着无论输入数据的大小如何，它都需要恒定的内存量。
2. 2. Inthe context of computer science, space complexity refers to the amount of memory required by an algorithm to store its variables and data structures.
   在计算机科学的背景下，空间复杂度是指算法存储其变量和数据结构所需的内存量。
3. 3. To optimize the space complexity, we need to consider how to reduce the number of objects that need to be storedin memory.
   为了优化空间复杂度，我们需要考虑如何减少需要存储在内存中的对象数量。
