The final min leftist tree is as follows:
5
/ \
7 10
/ \
13 8
/
11
Your output in level order is as follows:
[5,7,10,13,8,11]
The final min binomial heap is as follows:
5  7
 
10 13  8

11
Your output in level order is as follows:
(Note: elements in the same level could be displayed in any order)
Level 1: [5,7]
Level 2: [10, 13, 8]
Level 3: [11]
