Assume I tweak foo and add an $O(n \log m)$ work inside each call, that would just be multiplied for the time complexity, i.e., Time complexity = O(unique calls) * O(work-per-call), $Space Complexity = O(unique calls) * O(space per call), Now just reinforce these ideas with this question. We would never compute the value of the function twice for the same value, ever. 4 Here is a list I gathered a few weeks ago: Arabic (Youtube Videos and Playlists): I hope you like it.
