/**
 * Problem
 *
 * You're watching a show where Googlers (employees of Google) dance, and then
 * each dancer is given a triplet of scores by three judges. Each triplet of
 * scores consists of three integer scores from 0 to 10 inclusive. The judges
 * have very similar standards, so it's surprising if a triplet of scores
 * contains two scores that are 2 apart. No triplet of scores contains scores
 * that are more than 2 apart.
 *
 * For example: (8, 8, 8) and (7, 8, 7) are not surprising. (6, 7, 8) and (6, 8,
 * 8) are surprising. (7, 6, 9) will never happen.
 *
 * The total points for a Googler is the sum of the three scores in that
 * Googler's triplet of scores. The best result for a Googler is the maximum of
 * the three scores in that Googler's triplet of scores. Given the total points
 * for each Googler, as well as the number of surprising triplets of scores,
 * what is the maximum number of Googlers that could have had a best result of
 * at least p?
 *
 * For example, suppose there were 6 Googlers, and they had the following total
 * points: 29, 20, 8, 18, 18, 21. You remember that there were 2 surprising
 * triplets of scores, and you want to know how many Googlers could have gotten
 * a best result of 8 or better.
 *
 * With those total points, and knowing that two of the triplets were
 * surprising, the triplets of scores could have been:
 *
 * 10 9 10 6 6 8 (*) 2 3 3 6 6 6 6 6 6 6 7 8 (*)
 *
 * The cases marked with a (*) are the surprising cases. This gives us 3
 * Googlers who got at least one score of 8 or better. There's no series of
 * triplets of scores that would give us a higher number than 3, so the answer
 * is 3.
 *
 * Input
 *
 * The first line of the input gives the number of test cases, T. T test cases
 * follow. Each test case consists of a single line containing integers
 * separated by single spaces. The first integer will be N, the number of
 * Googlers, and the second integer will be S, the number of surprising triplets
 * of scores. The third integer will be p, as described above. Next will be N
 * integers ti: the total points of the Googlers.
 *
 * Output
 *
 * For each test case, output one line containing "Case #x: y", where x is the
 * case number (starting from 1) and y is the maximum number of Googlers who
 * could have had a best result of greater than or equal to p.
 *
 * Limits
 *
 * 1 â¤ T â¤ 100. 0 â¤ S â¤ N. 0 â¤ p â¤ 10. 0 â¤ ti â¤ 30. At least S of the ti values
 * will be between 2 and 28, inclusive.
 *
 * Small dataset
 *
 * 1 â¤ N â¤ 3.
 *
 * Large dataset
 *
 * 1 â¤ N â¤ 100.
 *
 * Sample
 *
 * Input Output 4 Case #1: 3 3 1 5 15 13 11 Case #2: 2 3 0 8 23 22 21 Case #3: 1
 * 2 1 1 8 0 Case #4: 3 6 2 8 29 20 8 18 18 21
