Calculate the height of a tree using a segment tree data structure.
A segment tree is a binary tree used for storing intervals or segments.
Each node represents an interval and stores information about that interval.
To find the height, recursively calculate the height of left and right subtrees.
Example: For a tree with nodes 1, 2, 3, the height is 2 (root + 1 level).
Height can be defined as the number of edges in th...

BFS uses a queue to keep track of nodes to explore next.
It starts from a source node and explores all its neighbors before moving to the next level.
Example: Finding the shortest path in an unweighted graph.
BFS can be implemented using an adjacency list or matrix.
It is useful in scenarios like social netw...

Helps in counting distinct elements in a sliding window. Example: Count distinct characters in a substring.
Efficiently solves problems like longest substring without repeating characters ...
The knapsack problem is a classic optimization problem that involves selecting items to maximize value without exceeding weight capacity.
The problem can be solved using dynamic programming.
Given weights and values of items, the goal is to maximize total value within a weight limit.
Example: If you have items with weights [1, 2, 3] and values [10, 15, 40], and a capacity of 6, the optimal selection is items 2 and 3.
