Write pseudocode for a ReAct-style loop

Q: Write pseudocode for a ReAct-style loop

This question evaluates the ability to design a ReAct-style agent control loop and related competencies such as state management, tool orchestration, observation handling, error management, and safeguards for termination and resource limits.

Q: How do I approach Coding & Algorithms interview questions?

Coding & Algorithms questions require understanding of core concepts and practice. PracHub provides solutions with explanations to help you master coding & algorithms interviews.

Question

Coding prompt (pseudocode)

Write pseudocode (does not need to compile) for a ReAct-style agent loop that alternates between reasoning and actions.

Requirements

The agent receives a user question .
On each iteration, the model produces something like:
- Thought : internal reasoning about what to do next
- Action : the name of a tool to call (e.g., Search , Calculator , LookupDB ) or Finish
- ActionInput : arguments for the tool
If an Action is chosen:
- Call the tool, obtain an Observation .
- Append Observation back into the context for the next iteration.
Stop when the model chooses Finish or when a maximum number of steps is reached.
Include basic safeguards:
- max steps / timeouts
- handling tool errors
- preventing infinite loops

Deliverable

Provide the loop structure and the data you keep in state (e.g., conversation history, scratchpad, tool outputs).
