What are some examples of space complexity in algorithms?

Space complexity refers to the amount of memory an algorithm uses relative to the input size. For example, a simple algorithm that uses a fixed number of variables has a constant space complexity, O(1).

Can you give me a specific example of an algorithm with linear space complexity?

Sure! A common example is the merge sort algorithm, which requires additional space proportional to the input size for the temporary arrays used during the merging process.

What about an example of an algorithm with exponential space complexity?

An example of exponential space complexity is the recursive implementation of the Fibonacci sequence, where each function call creates new stack frames, leading to a rapid increase in memory usage.

How can I reduce space complexity in my algorithms?

You can reduce space complexity by using iterative approaches instead of recursion, reusing variables, or using data structures that require less memory.
