Oh ya sorry. I thought we have to retrieve kth min and max, in which case heap can be used.
Here, we can either use stack or map. Map can be from a date(which increases by 1 daily) to a value, as only one value is received per day. Keeping in mind memory constraints, stack is better. Map is an otherwise safe solution. regards.
