Need to know: Dictionary, for loop  def count_characters(string): counts = {} for char in string: if char in counts: counts[char] = counts[char] + 1 else: counts[char] = 1 return counts # Example...

An anagram is word switch or word play. It is the result of rearranging the letters of a word or phrase to produce a new word or phrase, while using all the original letters only once. In interviews, usually we are only bothered with words without spaces in t...

Palindrome Worse approaches Reversing the String:You can reverse the string (using slicing like s[::-1] in Python) and then compare it to the original. This is very concise but uses O(n) additional space. Recursion:A recursive approach can check the...

Yes, product design in system design interviews is a great place to start for a few reasons, especially considering your multidisciplinary background as a software engineer, prototyper, and technical artist. Here's why and how to approach i...

Event-driven programming is a programming paradigm where the program reacts to events, such as user actions, sensor inputs, or system-generated signals. Instead of following a strict sequence of commands, the program listens for events and responds when they o...

Functional programming (FP) is a programming paradigm focused on writing software by composing and applying pure functions, avoiding shared state, and minimizing side effects. It's particularly well-suited for mathematical computations, data transformations, a...

The brute force approach tries every possible combination to check for a solution, without leveraging any special properties or optimizations of the data (such as sorted order). Typically involves:  Nested loops Outer Loop traverses the array for the fir...

In "The Organized Mind," Daniel J. Levitin explores how the modern world’s overwhelming amount of information impacts our ability to think clearly and make decisions. Drawing on insights from psychology, neuroscience, and cognitive science, Levitin provides ...

If possible. Ask what is the biggest problem the role is trying to soive 1–2 minutes = 250–300 words → Ideal for most interview answers 3+ minutes = 400+ words → Use for case studies or portfolio reviews, if asked  And always end with “did that ...

Sweet! Here are a few 3D math-flavored Python coding interview questions tailored for tech art — with increasing difficulty. I can go over answers/solutions with you too whenever you're ready. 🟢 Easy: Vector Basics 1. Find the direction vector between two ...

🗂️ Python File Handling — Q & A (with code) Q1: How do you read a file line-by-line safely in Python? A: with open('data.txt', 'r') as f: for line in f: print(line.strip()) Q2: How do you write a list of lines to a file in Python? A: ...

🟢 Standard Use when you want to loop directly over the items (values only). Input Example Output ["apple", "banana"] for fruit in ["apple", "banana"]: print(fruit) apple banana "hi" for char in "hi": print(char) h i { "a": 1,...
