+#=============================================================================
+# Copyright (c) 2023, Bob Lied
+#=============================================================================
+# You are given an array of integers in which all elements are unique.
+# Write a script to perform the following operations until the array is
+# empty and return the total count of operations. If the first element is
+# the smallest then remove it otherwise move it to the end.
+# Example 1 Input: @int = (3, 4, 2)
+#           Ouput: 5
+#   Operation 1: move 3 to the end: (4, 2, 3)
+#   Operation 2: move 4 to the end: (2, 3, 4)
+#   Operation 3: remove element 2: (3, 4)
+#   Operation 4: remove element 3: (4)
+#   Operation 5: remove element 4: ()
+
+# Example 2 Input: @int = (1, 2, 3)
+#           Ouput: 3
+#   Operation 1: remove element 1: (2, 3)
+#   Operation 2: remove element 2: (3)
+#   Operation 3: remove element 3: ()
