Coding (Algo)

Products without Each Entry

Algorithm: Prefix sum Difficulty: Medium Time: 30 minutes

Goal

Return an array where output[i] is the product of all nums entries except nums[i] without using division.

What this task practices

Products without Each Entry is a coding (algo) interview exercise that trains prompt interpretation, explicit assumptions, a concrete response, and a clear explanation of tradeoffs. The catalog marks it as medium difficulty. It focuses on Technical Reasoning, Testing, Validation. The signed-in workspace provides the tools for the round and evaluates the attempt against task-specific criteria. Reference solutions, hidden checks, evaluator instructions, and candidate work remain private.
