Median of stream of integers

#1

I have asked the doubt before also but its not been cleared.What correction do I need to make in my code?

Its giving correct answer for the test data but its not correct for the other test datas

#2

Modified Code

code and logic is correct but the problem is with statement
if (first.size() - second.size() > 1)
{
instead of this if you use if (first.size()>second.size()+1)
{

it will pass all testcase
