What is the complexity of each code sample and which is more optimized
//code one
$allocation_template->allocations()->each(function ($allocation){$allocation->forceDelete();});
// code two
Allocation::where('allocation_template_id', $allocation_template->id)->forceDelete();
Both code samples achieve the same result, which is to delete all allocations associated with a given allocation template. However, the second code sample is more optimized because it uses a single database query to delete all the records, whereas the first code sample uses a separate query for each allocation record.
The complexity of the first code sample is O(n), where n is the number of allocation records associated with the allocation template. The complexity of the second code sample is O(1), regardless of the number of allocation records.
The first line of code uses the each method to iterate over a collection of Allocation models related to a specific AllocationTemplate model, and then calls the forceDelete method on each of them. The time complexity of this operation is O(n), where n is the number of Allocation models related to the AllocationTemplate.
The second line of code uses the forceDelete method to delete all Allocation models associated with the AllocationTemplate model in the database directly. The time complexity of this operation is also O(n), where n is the number of Allocation models related to the AllocationTemplate.
Both of these codes have the same time complexity, so neither one is more optimized than the other in terms of time complexity. However, the first code may be more efficient in terms of memory usage as it deletes the Allocation models one at a time, whereas the second code deletes all of them in a single database query. Which one to choose depends on the specific use case and the amount of data being handled.
