 /**
- *
  * If you have a list
  * nums = [1, 3, 5, 7, 8, 13, 20]
  * then it is possible to slice by using a notation similar to element retrieval:
- *
+ * <p>
  * nums[3]   #equals 7, no slicing
  * nums[:3]  #equals [1, 3, 5], from index 0 (inclusive) until index 3 (exclusive)
  * nums[1:5] #equals [3, 5, 7, 8]
  * nums[-3:] #equals [8, 13, 20]
  * nums[3:] #equals [8, 13, 20]
- *
+ * <p>
  * Note that Python allows negative list indices. The index -1 represents the last element, -2 the penultimate element, etc.
  * Python also allows a step property by appending an extra colon and a value. For example:
- *
+ * <p>
  * nums[3::]  #equals [7, 8, 13, 20], same as nums[3:]
  * nums[::3]  #equals [1, 7, 20] (starting at index 0 and getting every third element)
  * nums[1:5:2] #equals [3, 7] (from index 1 until index 5 and getting every second element)
