Is there any tool available through which we can get Space and Time Complexity of our code in Big O notation?
With complex cases I use GPT. It breaks it down by every step, so far it’s given good info. More on reddit.com

The unsolvability of the halting problem means that you can't even reliably tell whether an algorithm will terminate in a finite amount of time. And IIRC, you can generalize the same kind of proof to show that no algorithm can reliably determine the time complexity of a piece of code, even if you're allowed to assume its running time is finite. If you use simple heuristics like counting the number of loops, your algorithm will be wrong in fairly predictable ways. If you use an LLM, your algorithm might have higher accuracy on typical examples, but the cases where it fails will be extremely hard to predict or anticipate. More on reddit.com
