The order of elements can be changed. It doesn't matter what you leave beyond the new length. --- ⏱ Time Complexity: O(n) 💾 Space Complexity: O(1) 💡 Key Concept: Use two pointers to overwrite unwanted elements and keep only valid ones. --- This is a common coding interview problem asked by companies like Amazon, Google, and Microsoft. --- 🔗 Connect with me: LinkedIn: https://www.linkedin.com/in/dashrat-rajpurohit/ X (Twitter): https://x.com/Dashrat_Singh_ GitHub: https://github.com/DashratRajpurohit --- If you're preparing for DSA or coding interviews, mastering in-place array manipulation is essential. #leetcode #removeelement #twopointers #codinginterview #dsa
