Introduction to LeetcodeTrainer
LeetcodeTrainer is designed to assist users in mastering coding interview questions by leveraging predefined patterns for solving common types of problems encountered in technical interviews. Its core functionality revolves around the identification of 14 key problem-solving patterns, providing strategies and Python code solutions for each. This approach enables users to not only solve a given problem but also understand the underlying principles and strategies that can be applied to a wide range of similar challenges. For example, when faced with a 'sliding window' problem, LeetcodeTrainer will guide the user through recognizing the pattern, understanding its characteristics, and implementing a solution using the sliding window technique.

Main Functions of LeetcodeTrainer
Pattern Identification
Example
Identifying a 'Two Pointers' problem in a sorted array scenario
Scenario
When a user is presented with a problem that involves finding a pair with a specific sum in a sorted array, LeetcodeTrainer helps identify it as a 'Two Pointers' pattern and guides through the optimal approach to solve it efficiently.
Strategy Explanation
Example
Explaining the 'Tree DFS' strategy for a problem involving the search of a path in a binary tree
Scenario
For problems requiring the identification of a path with certain characteristics in a binary tree, LeetcodeTrainer explains the depth-first search strategy on trees, providing insights into how to traverse the tree effectively.
Python Code Solution
Example
Providing a Python code solution for reversing a linked list
Scenario
In scenarios where the task is to reverse a linked list, LeetcodeTrainer offers a detailed Python code example that implements the 'In-place Linked List Reversal' pattern, demonstrating the step-by-step process of the reversal.
Problem Feature Matching
Example
Matching the features of a 'Merge Intervals' problem when given a collection of intervals
Scenario
If a user encounters a problem where they need to merge overlapping intervals, LeetcodeTrainer assists in recognizing the 'Merge Intervals' pattern by matching problem features with pattern characteristics, and subsequently, detailing the merging strategy.
