Spent 3 hours debugging a production issue last week. Turned out someone had named a variable "data" inside a function that also used an outer "data" variable.
No error. No warning. Just completely wrong output silently the whole time.
Please, for the love of everything, give your variables actual names. "data", "info", "temp" and "obj" are not variable names, they're apologies.

Solved a Gray Code problem in C++ today.
The task was to generate bit patterns from 0 to 2^n - 1 such that every consecutive pattern differs by only one bit, while always starting from 0.
I used the Gray code formula:
gray = i ^ (i >> 1)
This makes the solution clean and efficient, and guarantees that adjacent codes differ by exactly one bit.
Example for n = 2:
00 -> 01 -> 11 -> 10
What I like about this problem is how a simple bit manipulation formula can solve what looks like a complex sequence-generation challenge.
Concepts practiced:
Bit Manipulation
Binary Representation
Pattern Generation
C++ Problem Solving

🚀 Constructors and Destructors: Object Initialization and Cleanup (C++)
Constructors are special member functions in C++ that are automatically called when an object is created. They are used to initialize the object's data members and ensure that the object is in a valid state. Destructors are also special member functions that are automatically called when an object is destroyed. They are used to release any resources held by the object, such as dynamically allocated memory, preventing memory leaks. Constructors and destructors are crucial for proper object lifecycle management.

Invert Binary tree
Approach:
check if node is null or not if null return null
swap left node and right ( not value complete node )
go to left (recursively)
go to right (recursively)
return node
TC: O(N)
SC:O(N)- recursive stack

Stop memorizing Rust rules. Start deriving them. 🦀
This free interactive course reframes the borrow checker not as a set of rules to memorize, but as the logical outcome of three primitives: Space, Time, and Coordinates. 📐
Every memory bug is just a failure in one of these three dimensions:
🔸 Use-after-free
🔸 Dangling pointer
🔸 Data race
🔍 Understand the framework, and the compiler's behavior clicks into place. ✅
💡 Highly recommended for experienced devs, especially those with a C/C++ background.

The C compilation process transforms source code into an executable through four key stages: Preprocessing (handling macros), Compilation (converting code to assembly), Assembly(generating binary object code), and Linking (merging libraries). This sequence ensures human-written logic is correctly mapped to hardware for execution. Understanding this flow is vital for efficient debugging and optimizing software performance.

🚀 Nested `if-else` Statements in C++
Nested `if-else` statements involve placing one `if` or `if-else` statement inside another. This allows for more complex decision-making processes with multiple conditions. In C++, nesting can create a hierarchical structure where each `if` condition depends on the outcome of the previous one. Proper indentation is crucial for readability and to avoid logical errors. Excessive nesting can make code difficult to understand and maintain, so consider alternative approaches for complex logic.

Built a custom string handling class in C++ from scratch — without using std::string.
This project focuses on:
• Dynamic memory management using new[] and delete[]
• Implementation of the Rule of Three (Destructor, Copy Constructor, Copy Assignment)
• Manual string manipulation algorithms (reverse, case conversion, word counting)
• Operator overloading for intuitive usage (+, +=, [], (), comparison operators)
The goal was to deeply understand how strings work internally rather than relying on built-in abstractions.
A great exercise in mastering memory management, object-oriented programming, and low-level string operations in C++.
