Written questions: Number of minimum difference after sorting

Written question: To choose 2 persons from 5 people as a courtesy, of which each person's height range is 160-190, 2 people are required to the minimum height difference (if the difference is the same, select the highest of the two), in order to output two people in ascending height. Smple input:161 189 167 172 188 Sample output:188 189
