Curated External Problems

Core

Problem	Source	Difficulty	Context	Style	Prerequisites	Tags	Why it fits
Hidden Integer	CSES	Easy-Medium	Interactive	-	-	Binary Search; Query Budget; Flushing	Excellent first interactive problem for disciplined I/O and query budgeting.
Colored Chairs	CSES	Medium	Interactive	-	-	Parity; Binary Search; Query Budget	Small-query interactive problem that trains calm invariant tracking.
Hidden Permutation	CSES	Medium	Interactive	-	-	Comparison Oracle; Reconstruction; Query Strategy	A clean interactive reconstruction problem that trains protocol handling and comparison-based strategy.
K-th Highest Score	CSES	Medium	Interactive	-	-	Merge Logic; Query Strategy; Two Sorted Sources	Good practice for interactive strategy design under a global query cap.
Permuted Binary Strings	CSES	Medium	Interactive	-	-	Bit Probing; Reconstruction; Query Design	A reconstruction problem that rewards careful experiment design.
Inversion Sorting	CSES	Hard	Interactive	-	-	Sorting By Feedback; Adaptive Strategy; Interaction Protocol	Great later-stage interactive practice where the judge feedback is indirect.
