Taschenbuch. Zustand: Neu. Neuware - Fourteen days of drills that turn design patterns from vocabulary into judgment. Most pattern books show you Java-shaped code and leave out the question C++ actually asks: who owns these objects, and how long do they live This one answers it for every pattern. That is the difference between a diagram you can recite and a design you can ship. You learn by doing, on one real project. studio is a command-line vector-drawing and report-generating application. It starts on Day 1 as a rigid hundred-line program and ends on Day 14 as a design that absorbs change. Every pattern earns its place in it rather than being bolted on. Week one builds the foundation: what a design is judged by, object lifetime and ownership in C++, and all five SOLID principles. Week two is the twenty-three classic patterns in their three groups, then the C++ forms that reach the same flexibility with no virtual function at all, then removing designs as well as adding them. Every pattern is presented the same way. First the change that breaks the rigid design. Then the rigid code, with the exact line you would have to edit. Then the hinge, the one abstraction that turns editing into adding. Then the code that changed. Then the cost, stated plainly, because a pattern that looks free gets used everywhere. Every day is self-contained: numbered rules, short worked examples with real captured output and a diagram of the mechanism, then a fixed ladder of five problem sets running from recall to unassisted building. Practice problems have no answers anywhere, by design. YOUR 14-DAY PATH Week 1 - Principles Day 1: Design, Change and Cost Day 2: Single Responsibility and Open-Closed Day 3: Substitution, Segregation and Inversion Day 4: Creating Objects by Name Day 5: Assembling, Copying and Sharing Day 6: Wrapping, Splitting and Nesting Day 7: Adding, Hiding, Deferring and Sharing Week 2 - Patterns and judgment Day 8: Interchangeable Behaviour Day 9: Objects That Talk to Each Other Day 10: Mode, Traversal and History Day 11: Operations over a Structure Day 12: Patterns without Virtual Functions Day 13: Anti-Patterns and Refactoring toward Patterns Day 14: The Assembled Application WHO IT'S FOR Working C++ programmers who can write a class but cannot yet say why one design survives a change and another does not. Students on a software design or software engineering course. Candidates preparing for a design interview, where the twenty-three patterns are asked about by name. Written to C++23. Every listing was compiled and run with g++ -std=c++23 -O2 -Wall -Wextra, and every printed output is what came back from that run. Nothing was typed from memory. Work the problems. That is what the book is for. …

Taschenbuch. Zustand: Neu. Neuware - Fourteen days of drills on the SQL a technical interview actually asks for, run through nothing but Python's own standard library. This is a drill manual, not a narrative course. Every listing was executed for real against a small SQLite database built up across the fourteen days, and every printed output block, including every EXPLAIN QUERY PLAN, is a paste from that run. Each chapter states a rule in as few words as it can, shows the rule working in a short numbered example with its captured output, and hands it straight back as problems. The vehicle is hiredb, one job-application database with four tables: applications, companies, contacts and a status-history log. Only Python 3.11 or later is required. sqlite3 ships in the standard library, so there is no server to install, no account to create, and no driver to configure. Every listing runs unchanged on Windows, macOS and Linux. The first week covers the ground a screen opens with: the table and the first query, SELECT and WHERE, every join type, GROUP BY and aggregate traps, subqueries and CTEs, window functions, and NULL and three-valued logic. The second week covers what separates a pass from a strong pass: indexes, reading a query plan, transactions and isolation, normalisation and schema design, calling SQL safely from Python, one full take-home task, and a closing chapter of forty timed questions, each worked and its own plan read. The findings are reported as they came out. A missing index turns a two-hundred-thousand-row filter from fourteen milliseconds into one tenth of one. A naive pay comparison shows remote roles earning nineteen points more than onsite ones, and the gap nearly disappears once role is held constant. Your 14-Day Path - 1. THE TABLE, THE ROW AND THE QUERY- 2. SELECT, WHERE AND THE FIRST QUESTIONS- 3. JOINS: INNER, LEFT AND THE ONE THAT LOSES ROWS- 4. GROUP BY, HAVING AND AGGREGATE TRAPS- 5. SUBQUERIES, CTEs AND READABLE SQL- 6. WINDOW FUNCTIONS- 7. NULL AND THREE-VALUED LOGIC- 8. INDEXES AND WHY YOUR QUERY IS SLOW- 9. READING A QUERY PLAN- 10. TRANSACTIONS AND ISOLATION- 11. NORMALISATION AND SCHEMA DESIGN- 12. SQL FROM PYTHON- 13. THE TAKE-HOME DATA TASK- 14. THE LIVE SQL SCREEN Who It's For Job seekers preparing a technical screen or a take-home assignment. Students learning SQL through Python's own standard library. Working developers whose SQL has stayed at a beginner's level for years. Anyone who wants every answer checked against a real database, not memorized. 284 worked examples. 286 figures. 650 numbered problems. 392 pages. Built and measured against Python 3.11 and SQLite 3.38. You need only Python and about an hour a day. Start Day 1.…

Taschenbuch. Zustand: Neu. Neuware - Fourteen days of drills on the patterns a coding interview actually asks for, run through nothing but plain Python and a harness built on Day 1. This is a drill manual, not a narrative course. Every listing was executed for real through drillkit, a small timing-and-testing harness the book builds and grows across fourteen days, and every printed output block is a paste from that run. Each chapter states a rule in as few words as it can, shows the rule working in a short numbered example with its captured output, and hands it straight back as problems. Only Python 3.11 or later is required. No package needs installing and no account needs creating. Every listing runs unchanged on Windows, macOS and Linux. The first week builds the model and the instruments: how a score is built from four axes, complexity spoken out loud, arrays and two pointers, hash maps, sliding windows, linked lists, and stacks and monotonic structures. The second week covers trees, graphs, recursion and backtracking, sorting and binary search, dynamic programming, heaps and greedy choices, and a closing mock loop of four timed interviews. The findings are reported as they came out. A heap-based merge loses to a single call to Python's own sort. A first-element quicksort pivot turns a fast sort thirty times slower on sorted input. Two candidates with identical, unfinished code cross a hiring threshold on one axis alone: the one who says what they would try next scores higher than the one who goes silent. Your 14-Day Path - 1. HOW A CODING INTERVIEW IS SCORED- 2. COMPLEXITY YOU CAN DEFEND OUT LOUD- 3. ARRAYS AND TWO POINTERS- 4. HASH MAPS AND COUNTING- 5. STRINGS AND SLIDING WINDOWS- 6. LINKED LISTS AND POINTER SURGERY- 7. STACKS, QUEUES AND MONOTONIC STRUCTURES- 8. TREES AND TRAVERSAL- 9. GRAPHS- 10. RECURSION, BACKTRACKING AND PRUNING- 11. SORTING AND BINARY SEARCH- 12. DYNAMIC PROGRAMMING WITHOUT PANIC- 13. HEAPS, INTERVALS AND GREEDY CHOICES- 14. THE MOCK LOOP Who It's For Bootcamp graduates and career changers preparing a first technical screen. Students who want every claim measured against a running program. Working developers whose interview skills have gone rusty. 280 worked examples. 336 figures. 630 numbered problems. 384 pages. Built and measured against Python 3.11. You need only Python and about an hour a day. Start Day 1.…
