Solution: Two Sum III - Data structure design
Understand how to design a custom data structure in JavaScript that handles a stream of numbers and enables quick checks for pairs summing to a given value. Explore implementing the TwoSum class with add and find methods using hash maps to optimize lookups and frequency tracking for efficient problem solving.
We'll cover the following...
Statement
Design a data structure that takes in a stream of numbers and can check if any two numbers add up to a specific value.
Implement the TwoSum class with the following constructor and methods:
Constructor: Sets up the
TwoSumobject with an empty list at the start.void add(int number): Adds a new number to the list.
boolean find(int value): Returns TRUE if any two numbers in the list add up to the given value. If not, it returns FALSE.
Constraints:
