# GrindLeet > Master coding interviews with NeetCode 150 and Striver's SDE Sheet. 400+ problems with detailed C++ solutions, organized by pattern and difficulty. GrindLeet is a free coding interview preparation platform. It provides two complete, curated problem sets — NeetCode 150 and Striver's SDE Sheet — with battle-tested C++ solutions, approach explanations, time/space complexity analysis, and algorithm templates. ## Features - **NeetCode 150**: 150 handpicked LeetCode problems across 18 topic patterns (Arrays & Hashing, Two Pointers, Sliding Window, Stack, Binary Search, Linked List, Trees, Tries, Heap/Priority Queue, Backtracking, Graphs, Advanced Graphs, 1-D Dynamic Programming, 2-D Dynamic Programming, Greedy, Intervals, Math & Geometry, Bit Manipulation). Filter by Easy, Medium, or Hard difficulty. - **Striver's SDE Sheet**: 180+ problems organized by topic with sticky navigation. Covers arrays, linked lists, greedy, recursion, binary search, heaps, stacks, queues, strings, trees, graphs, dynamic programming, and tries. - **Algorithm Templates**: Ready-to-use C++ code templates for common algorithmic patterns including Binary Search, Two Pointers, Sliding Window, BFS/DFS, Union Find, Topological Sort, Dijkstra's, and more. Each template includes when-to-use guidance and complexity analysis. - **Progress Tracking**: Sign in to track completed problems and stay motivated. - **Difficulty Filtering**: Filter problems by Easy, Medium, or Hard. - **Shuffle Mode**: Randomize problem order for varied practice. ## Pages - [Home](/): Landing page with overview and navigation - [NeetCode 150 Problems](/problems): Browse and study all 150 NeetCode problems - [Striver's SDE Sheet](/striver): Browse Striver's curated problem set by topic - [Algorithm Templates](/templates): Battle-tested C++ algorithm templates ## Topics Covered Arrays & Hashing, Two Pointers, Sliding Window, Stack, Binary Search, Linked List, Trees, Tries, Heap / Priority Queue, Backtracking, Graphs, Advanced Graphs, 1-D Dynamic Programming, 2-D Dynamic Programming, Greedy, Intervals, Math & Geometry, Bit Manipulation ## Target Audience Software engineers and computer science students preparing for technical coding interviews at companies like Google, Meta, Amazon, Apple, Microsoft, and other top tech companies. ## Tech Stack React, TypeScript, Tailwind CSS, Vite
