Alogrithms
Master essential algorithms for coding interviews including sorting, searching, recursion, dynamic programming, and graph algorithms.
Heap Sort Algorithm
Heap Sort uses a binary heap to repeatedly move the largest element to the end of the array,...
Radix Sort Algorithm
Radix Sort sorts integers digit by digit, using a stable subroutine such as Counting Sort for each digit...
Cyclic Sort
Cyclic sort is an in-place array technique that runs in O(n) time and uses O(1) extra space. It’s...
Divide and Conquer
Divide and Conquer is a core algorithmic paradigm for solving complex problems by breaking them into smaller, similar...
Dynamic Programming
Dynamic programming (DP) is one of the most powerful algorithmic techniques in computer science. It's a favorite topic...
Merge Sort
Many sorting problems in technical interviews require more than basic knowledge of sorting. While simpler algorithms like Bubble...
Prefix Sum
In coding interviews, many array problems involve answering repeated range-based questions, such as computing sums or counts over...
Depth First Search
Depth-First Search (DFS) is more than just a graph traversal technique. It is a fundamental recursive exploration strategy...
Binary Search
Binary Search is one of the highest-ROI topics for coding interviews. It’s fast, elegant, and shows up frequently:...
