Applications of Segment Trees
- Segment Trees are used to answer range queries like finding the minimum, maximum, sum, greatest common divisor, least common multiple, etc., in an array in logarithmic time.
- Segment Trees can handle updates and modifications in the data structure.
- Segment Trees can be used with a technique called Lazy Propagation to perform range updates in logarithmic time.
- Segment Trees are used to solve the Range Minimum Query problem, which aims to find the minimum element from a range in an array.
- Segment Trees can also solve the Range Maximum Query problem, which aims to find the maximum element from a range in an array.
- Segment Trees can be used to find the count of distinct elements in a range.
- Segment Trees can be used to find the K-th number in a sequence.
Segment Tree in C
A Segment Tree is a data structure in C that helps us quickly perform operations (like finding the sum, minimum, or maximum) on a range of elements in an array. It’s like a tree that stores information about parts of the array in each node.
In this article, we will learn what are segement trees, how they work and how to implement them in C language.
