数组最小值查找优化提示（学生作业，仅需提示勿给答案）

Hey! I get that you're working on a school assignment with an array program, and while most features are solid, you're feeling the min-value lookup could be more efficient—plus you're unsure about how it ties into your array construction. Here are some targeted thought prompts to guide your optimization:

• Think about when you're building the array: instead of waiting until the entire array is constructed to start checking for the minimum, could you track a candidate value as you add each element? That way you avoid a full post-construction traversal.
• Audit your current lookup approach: how many times are you iterating over the array? If other parts of your program also loop through the array, is there a way to combine the min-check with those existing operations to cut down on redundant passes?
• Consider the structure of your array: does it have any inherent order (even partial) that you could leverage? For example, if certain segments are sorted, you might not need to compare every single element to find the overall minimum.
• Break down the time complexity: what's the asymptotic complexity of your current method? While the optimal theoretical complexity for an unsorted array is fixed, you can look for ways to reduce constant factors—like minimizing unnecessary variable assignments or comparisons during the loop.
• If you're using any helper functions or extra data structures for the lookup, ask yourself: do these add more overhead than they save? Sometimes simpler, in-line checks can outperform more "complex" approaches for small to medium-sized arrays.
