1
5 2
5 1 3 5 2
so first 5 comes… till then only one number is present and we have to find top 2 frequent numbers so o/p is 5
then 1 comes so o/p is 1 5
then 3 comes and o/p is 1 3
then 5 comes… now we have 2 instances of 5… so o.p is 5 1
then 2 comes… so o/p is 5 1

thus overall o/p i 5 1 5 1 3 5 1 5 1
