Technical Interview Question: Counting Squares from Points

Prompt

You are given a vector of points in 2D space, represented as Vec<(i32, i32)>. Write a function that returns the number of distinct squares that can be formed using these points as vertices.

A square is defined as a quadrilateral with four equal sides and four right angles.

Subscriber Program Design Document

Overview

The Subscriber program manages subscription tiers for Switchboard oracle data access. Users burn payment tokens (SWTCH or other configured tokens) to subscribe to different service levels that control data delivery latency, rate limits, and streaming capacity. Each accepted payment token has a configurable multiplier that affects subscription duration.

Program ID

// TBD - Will be generated during deployment

Assignment 1 — Docs Review (Switchboard)

Review docs.switchboard.xyz and the Switchboard Examples repository.

Prompt

Which sections lack clarity, feel incomplete, or are out of order?
Propose 3 concrete improvements (titles, placement, code, diagrams, examples).
For each, explain why it helps adoption and where it should live in the nav.
