Nettet10. apr. 2024 · In merge, you do allocate_memory [nee malloc] for tmp1 and tmp2 but never call free [or whatever] for them. So, you're leaking memory. Even if you do the free, this is slow because the time to do the alloc/free will exceed the time of the function. You can solve this by having an outer function that does the alloc/free once for the … NettetMethod to sort an array in-place. argsort Indirect sort. lexsort Indirect stable sort on multiple keys. searchsorted Find elements in a sorted array. partition Partial sort.
