@mailmeanmolbansal have u found the error in my code yet?

@himanshukumarclassic37.hk
for handling duplicate numbers we need to keep Count of Arrays,using
HashMap<Integer,Integer>.
The approach is to build HashMap from first array with count,then decrement the HashMap using Array2.
And print while traversing the Array2.

@mailmeanmolbansal I have done the required changes in my code but still number 2 is printing three times.

@himanshukumarclassic37.hk
Changes to be made
1 .We have to print the sorted list(use Collections.sort) to sort the list.
2. We have to only add in the result list when the element searched have frequency greater than 0.
I made above two changes and it passed.
Please make above changes and revert back.
