could u plz explain the sample input and output?
Top k most frequent numbers in a stream
input :
testcase=1
n=5 k = 2
arr[] = {5, 1, 3, 5, 2}
Output : 5 1 5 1 3 5 1 5 1
Explanation:
After reading 5, there is only one element 5 whose frequency is max till now.
so print 5.
After reading 1, we will have two elements 1 and 5 with the same frequency.
As 1, is smaller than 5 but their frequency is the same so we will print 1 5.
After reading 3, we will have 3 elements 1, 3 and 5 with the same frequency,
so print 1 3.
After reading element 5 since 5 has already occurred so we have now a
frequency of 5 as 2. So we keep 5 at the top and then rest of the element
with the same frequency in sorted order. So print, 1 5 1.
