LeetCode_Tasks

These are tasks I solve for practice over the time from the LeetCode site. All of the problems are solved using C++ language and are mainly linked with Data Structure and Algorithms.

The main data types in the problems are:

Dynamic Array
String
Stack
Queue
Linked List(Singly)
Doubly Linked List
Cycled List
Trees
Binary Search Trees
Binary Ordered Trees
Graphs(BFS, DFS)
Hash Functions and Hash Tables
Heap(Min & Max)
Sorting Algorithms
Sets
