Problem:

Given an array of scores sorted in increasing order, return true if the array contains 3 adjacent scores that differ from each other by at most 2, such as with {3, 4, 5} or {3, 5, 5}.

scoresClump({3, 4, 5}) → true
scoresClump({3, 4, 6}) → false
scoresClump({1, 3, 5, 5}) → true

Solution:

public boolean scoresClump(int[] scores) {
  if (scores.length < 3)
    return false;
  
  for (int i = 0; i < scores.length-2; i++) {
    if (scores[i+2] - scores[i+1] <= 2 && scores[i+2] - scores[i] <= 2)
      return true;
  }
  return false;
}
