Pin Claude Code to Opus 4.6 (1M context) — CLI + VS Code

Set a default model for both the Claude Code CLI and the VS Code extension. They share the same global config, so one change covers both.

TL;DR

Add a model key to your global user settings at ~/.claude/settings.json:

{

# ============================================================
# 1. UNION FIND (Disjoint Set Union)
# ============================================================
# Use case: Connected components, cycle detection in graphs
# Example: Number of Islands (LC 200)

class UnionFind:
    def __init__(self, elements):
        self.parent = {e: e for e in elements}
        self.size = {e: 1 for e in elements}
