Solution: Maximum Frequency Stack
Explore how to implement a maximum frequency stack in C# that supports push and pop operations in constant time. Understand the use of hash maps and stacks to track element frequencies and retrieve the most frequent elements, including resolving ties based on recency. This lesson equips you to solve complex data structure problems efficiently, preparing you for coding interviews.
Statement
Design a stack-like data structure. You should be able to push elements to this data structure and pop elements with maximum frequency.
You’ll need to implement the FreqStack class that should consist of the following:
-
FreqStack: This is a class used to declare a frequency stack.
-
Push(value): This is used to push an integer data onto the top of the stack.
-
Pop(): This is used to remove and return the most frequent element in the stack.
Note: If there is a tie for the most frequent element, then the most recently pushed element is removed and returned.
Constraints:
-
value -
At most, ...
