Sensor Drift Correlation

Two sensors record timestamps of specific seismic events. Both sensors provide timestamps in sorted order. Due to positioning, timestamps for the same event might differ slightly. Your task is to find the minimum absolute time difference between any event recorded by Sensor A and any event recorded by Sensor B. Input Format: Line 1: Space-separated integers representing timestamps from Sensor A. Line 2: Space-separated integers representing timestamps from Sensor B. Output Format: A single integer representing the minimum absolute difference. Example: Input: 1 5 10 15 3 8 12 Output: 2 (Explanation: The closest pair is (1, 3) or (10, 12) or (10, 8), all have a difference of 2.)
