Why Your Code is Slow (Stack and Heap Memory Explained)
Your code is logically perfect, so why is it still crawling? Today we explore raw pointers, local scopes, and exactly how memory location decides if your program survives a high stakes execution cycle.

Recurrent neural networks process sequences by propagating information through time via shared parameters.
A hidden state h receives input x via weight U and produces output o via weight W while connecting back to itself through recurrent weight V in the compact form.
The unfold operation expands this across time steps t-1, t and t+1, where each hidden state h_t incorporates the prior state via V along with the current input x_t via U to generate the corresponding output o_t via W.
It powers sequence prediction in applications such as next-word suggestion in keyboards.
Tensors generalize vectors as lists and matrices as grids into higher-order arrays like 3D cubes.
Comparisons include a vector as a list, a matrix as a grid, and a 3-tensor as a cube, along with the stress tensor σij on a cube featuring arrows for components like σ11 and σ23, the product derivative rule, the Riemann curvature tensor R(u,v)w = ∇u ∇_v w − ∇_v ∇_u w − ∇[u,v]w, quantum superposition 1/√2(|00⟩ + |11⟩), and algebraic operations like the tensor product.
It is used to analyze internal forces and deformations in engineering materials and to describe the geometry of spacetime under gravity in general relativity.
In 2016, a man with no CS degree quit his job to study for a Google interview.
He was an English major.
A self-taught web developer.
A former Korean translator in the US military.
He studied 8 to 12 hours a day. For 8 months straight.
Algorithms. Data structures. System design. Operating systems. Networking. Every topic Google asks.
He tracked every minute of it on GitHub. He called the repo "Google Interview University."
Then he applied to Google.
Google never called him back.
Here's the wildest part:
The repo he left behind became one of the most-starred projects on GitHub. Over 343,000 stars. Used by thousands of devs to break into FAANG.
He got hired at Amazon as a Software Engineer.
His name is John Washam. The repo is now called coding-interview-university.
Inside you get:
- A multi-month study plan, week by week
- Every CS topic Google, Amazon, Meta and Microsoft actually ask
- Algorithm patterns with worked examples
- System design from zero to senior
- Big-O, data structures, trees, graphs, recursion, dynamic programming
- Behavioral interview prep
- Mock interview drills
- Book and lecture recommendations he personally used
- Flashcards, video resources, and a coding question practice plan
Self-paced. Free. No course. No paywall. No upsell.
Just one engineer's 8-month study log, open for anyone who wants to follow it.
If you are preparing for a tech interview, this is the most complete free roadmap on the internet.
100% Open Source.
