كيف يعمل، بلا مصطلحات زائدة
Prime Factors should be understood through its invariant and the state it changes at each step.
The practical complexity in this reading is Varies by implementation / input constraints; always connect that cost to the actual loops, recursion, data structure operations or input assumptions.

State the mathematical identity/property.
Choose numeric representation and constraints.
Translate the property into an iterative/recursive computation and analyze precision.
Read a tiny input by hand and write down the state after every important operation. For Prime Factors, the goal is to make the invariant visible rather than to memorize code.
Varies by implementation / input constraints
Do not quote this complexity mechanically. Ask which operation or input dimension it describes, then derive the cost from the loops, recursion depth, data-structure operations and any preprocessing assumptions.
مناسب لـ
- Use the direct mathematical property when it removes unnecessary brute force.
ما الذي يسوء عادةً
- Ignoring floating-point precision or integer range.
- Using a formula outside its valid assumptions.
صيغة إجابة احترافية
A strong interview explanation of Prime Factors should cover the problem it solves, its invariant, the important data structure/state, its Varies by implementation / input constraints cost, and the constraint that would make you choose a different approach.

ماذا يجب أن أذكر عن التعقيد؟
Its typical cost here is Varies by implementation / input constraints, but a complete answer should connect that cost to the representation, input constraints and the dominant operations.
