Understand the problem
Restate the problem precisely. Interviewers reward candidates who pause, define the contract, and name the guarantees before coding.
Problem statement
Given an integer array `nums`, find a subarray that has the largest product, and return the product. The test cases are generated so that the answer will fit in a 32-bit integer.
Example
nums = [2,3,-2,4] → 6
Constraints
1 ≤ nums.length ≤ 2 · 10⁴ · −10 ≤ nums[i] ≤ 10
