+ *
+ * Given an unsorted array return whether an increasing subsequence of length 3 exists
+ * or not in the array.
+ * 
+ * Formally the function should:
+ * Return true if there exists i, j, k 
+ * such that arr[i] < arr[j] < arr[k] given 0 ≤ i < j < k ≤ n-1 else return false.
+ * Your algorithm should run in O(n) time complexity and O(1) space complexity.
+ * 
+ * Examples:
+ * Given [1, 2, 3, 4, 5],
+ * return true.
+ * 
+ * Given [5, 4, 3, 2, 1],
+ * return false.
