Task 2 — Deterministic Reduction

Core Track10 levelssolve locallysubmit final number

Levels unlock sequentially. Reveal the official input per level, reduce the sequence exactly as defined, and submit the final integer.

Level 1 — Absolute Difference

Difficulty: Mediumintegerswarmup
🔓 unlocked

Reduce left-to-right using the absolute difference.

[rule]
accᵢ = |accᵢ₋₁ - b|
[example]
input: 10 3 8
acc0 = 10
acc1 = |10 - 3| = 7
acc2 = |7 - 8|  = 1
answer = 1
Solve locally (Java), then submit only the final answer.
