+# Good Triplets: You are given an array of integers, @array and three integers $x,$y,$z.
+#   Write a script to find out total Good Triplets in the given array.
+#     A triplet array[i], array[j], array[k] is good if it satisfies the following conditions:
+#   a) 0 <= i < j < k <= n (size of given array)
+#   b) abs(array[i] - array[j]) <= x
+#   c) abs(array[j] - array[k]) <= y
+#   d) abs(array[i] - array[k]) <= z
+# Example1:
+#   In-put: @array = (3,0,1,1,9,7) and $x = 7, $y = 2, $z = 3
+#   Output: 4
+# Example2:
+#   In-put: @array = (1,1,2,2,3  ) and $x = 0, $y = 0, $z = 1
+#   Output: 0
