Product-Based DSA Roadmap: Pattern Mastery How to use: Focus on ONE pattern at a time. Do not move to the next pattern until you can solve the current pattern's problems without looking at the solution. Phase 1: The Essentials (Arrays & Strings) Pattern Problem Name Difficulty Link Two Pointers Sorted arrays, Pairs Valid Palindrome Easy Solve Squares of a Sorted Array Easy Solve Two Sum II - Input Array Is Sorted Medium Solve Con...

Majority Element in an Array Given an integer array nums of size n , the task is to find the majority element . A majority element is defined as the element that appears more than ⌊n / 2⌋ times in the array. It is guaranteed that the majority element always exists. Problem Example Input: nums = [3, 2, 3] Output: 3 Input: nums = [2,2,1,1,1,2,2] Output: 2 Approach 1: Using Counter (Easy to Understand) A straightforward approach is to count the frequency of each element and return the one with the maximum count. Python Code from collections import Counter class Solution: def majorityElement(self, nums): freq = Counter(nums) max_count = max(freq.values()) for key in freq: if freq[key] == max_count: return key Complexity Analysis Time Complexity: O(n) Space Complexity: O(n) Although this solution is simple and readable, it us...

The plan, which follows its underlying foundations back to the last part of the 1800s makes certain to track down a home on wired earphones, workstations, and different pieces of sound gear for quite a long time to come.  In the event that you've at any point pondered the attachment on your old arrangement of wired EarPods or different earphones for even a second as you go to pop it into a jack, you've definitely seen the series of little, shaded, plastic rings it has in fluctuating numbers from one fitting to another. What are those for? The work of an earphone attachment and jack really is basic: to convey sound signs from the source and send them to your earphone's the place where they're played as sound. These rings assume a significant part, not due to what they do, but since of what they...
