Purpose and Scope

This is a Java learning repository organized as a three-week, day-by-day set of standalone data-structure, algorithm, and language-feature exercises. It has no indicated unified application, build system, service layer, or deployment target.

Execution Model and Entry Points

Each .java file is an independently compilable exercise or demonstration, generally expected to be run directly when it contains a main method. There is no repository-wide launcher. Likely demonstration entry points include:

• Week_1/LibraryInterfaceDemo.java

• Week_2/package_live/Test.java

• Week_3/TestCompartment.java

Week 1: Arrays, Matrices, and Basic Strings

The first stage concentrates on array traversal, two-pointer/sliding-window methods, matrix iteration, and basic string operations. Problems are intentionally isolated rather than sharing a domain model.

• Week_1/Day_1/TwoSum.java

• Week_1/Day_3/ContainerWithMostWater.java

• Week_1/Day_4/SpiralMatrix.java

Week 2: String Algorithms and Java Package Demonstration

Week 2 advances into hash-based string operations, substring/permutation processing, recursion or stack-style decoding, and grouped transformations.

• Week_2/Day_2/PermutationOfStrings.java

• Week_2/Day_4/DecodeString.java

• Week_2/Day_5/GroupAnagrams.java

A separate package-oriented example models a small interface/implementation boundary: Playable is the contract and instrument classes supply implementations, consumed by a test driver.

• Week_2/package_music/Playable.java

• Week_2/package_music/string/Veena.java

• Week_2/package_live/Test.java

Week 3: Linked Structures, Stacks, and Queues

The final stage focuses on mutable linked-list operations and linear data structures. Individual classes encapsulate algorithmic state such as linked nodes, stack contents, or queue behavior; they do not form a shared reusable library.

• Week_3/Day_1/ReverseLL.java

• Week_3/Day_3/MinStack.java

• Week_3/Day_5/QueueUsingStack.java

Primary Data and Control Flow

Typical control flow is local: construct primitive arrays, strings, or linear data structures; execute an algorithm; return or print a result. Progression is pedagogical rather than runtime-driven: Week 1 covers contiguous data, Week 2 text and recursion-oriented tasks, and Week 3 pointer-based and stack/queue structures. Cross-file integration is limited to the package/interface examples.

Runtime and External Boundaries

The material runtime is the Java/JVM standard library. No external services, databases, APIs, frontend, cloud infrastructure, or dependency-management/build artifacts are present in the supplied tree. Package paths under Week_2/package_music are the principal explicit module boundary; all algorithm files otherwise appear self-contained.
