Python vs C++ in Interviews: Clear Thinking Trumps Syntax

Must try to solve the 2nd version of Leetcode problem: "Remove duplicates from unsorted array" if you have solved the first one... The upgraded problem is (problem 80)- "Given an integer array nums sorted in non-decreasing order, remove some duplicates in-place such that each unique element appears at most twice. The relative order of the elements should be kept the same." The logic slightly changes. Variable j is now initiated at 2 instead of 1 as in the 1st version. #dsa #leetcode #python #twopointersalgorithm #python #competitiveprogramming #algorithms #interviews #dailycoding #codingchallenge

This is a basic Python interview question, but it reveals whether your fundamentals are actually clear. The question looks simple: You copy a list in two different ways, modify the original list, and then check the output. What it really tests: • How Python handles object references • Difference between assignment vs slicing • Understanding of mutable data types Strong fundamentals make such questions obvious — weak ones make them confusing. If you’re preparing for Python interviews, don’t skip the basics.

This is how to find roots of a quadratic equation in Python. The code effectively finds real as well as complex roots using cmath.sqrt() function. #dsa #numbers #mathematics #equations #competitiveprogramming #python #algorithms #mathlogic #codingchallenges #interviews #programming

💡 Python Tip That Could Save Your Next Interview Ever heard of slots in Python? It’s a smart way to limit attribute creation and reduce memory usage especially in large-scale class designs. If you're prepping for tech interviews, this little trick can help you stand out by showing you understand performance optimization beyond the basics. 📌 Save this post for your study stack 💬 Share it with a friend who's brushing up on Python Visit us: https://itlearning.ai/ #itlearningai #PythonDev #PythonCode #PythonProgramming #PythonClasses #PythonSlots #TechInterviewTips

This Python interview question is a classic trap. It tests: • Mutability • Function memory behavior • Real Python fundamentals Understanding this prevents real-world bugs, not just interview failures. #Python #CodingInterview #SoftwareDeveloper #ProgrammingTips #TechCareers

Problem Statement: Reverse all the vowels present in a string and return string. This problem can be solved in linear time complexity O(n) using two pointers method where n is length of input string. However, since its a string, you will need extra space to store a list and then its joined string version, so O(n). #dsa #strings #competitiveprogramming #python #algorithms #leetcode #programming #datastructures #interviews

Mastering the sliding window technique is key for coding interviews. 🚀 A common challenge is counting subarrays with exactly k odd numbers. Since a direct approach can be tricky, the most efficient way to solve this in O(n) time is to use a helper function that counts subarrays with "at most k" odds. By calculating (at most k) - (at most k-1), you isolate the exact count effortlessly. This approach maintains O(n) time complexity and O(1) auxiliary space, making it ideal for large datasets. #DSA #Python #CodingInterview #SlidingWindow #Programming Link to code: https://lnkd.in/duSDQV9b

💡 This question looks simple, but it tests a very important Python concept: 👉 Difference between is (identity) and == (equality) Many beginners get confused here — and yes, this is a real interview-level trap question. 📌 Drop your answer in the comments and explain why you chose it.

Day 1: Revisiting a “Basic” Python Concept That Quietly Fails Interviews 🐍 I used to think I understood Python well until a single interview question on scope exposed a blind spot. The code looked completely fine. It still crashed. That moment pushed me to deeply understand why UnboundLocalError exists, not just how to fix it. What surprised me most was that the bug wasn’t about syntax, it was about how Python decides scope before execution. So I documented the mental model I wish I had earlier. Here’s the exact kind of code that breaks confidence in interviews: x = 10 def function(): print(x) x = 20 At first glance, this feels logical. But Python sees it very differently. In the doc, I break down: How Python scans functions before running them (definition vs execution) Why an assignment at the bottom of a function can break the top Why Python’s scope rules feel “backwards” if you come from Java or C++. 📄 I’ve shared the full explanation and reasoning in the document below. Feedback and corrections are welcome - this is part of me revisiting fundamentals properly. #Python #TechnicalInterviews #BackendDevelopment #MachineLearning #DataScience #DevCommunity #JuniorDeveloper #SelfTaughtDev #BestPractices #CodeQuality
