1721 - Swapping Nodes in a Linked List.

Hi, Today we will be solving leetcode qs 1721 - Swapping Nodes in a Linked List. This qs is really simple. We need to swap the nodes placed at k distance from the start and end of the Linked List. So let's suppose you have a Linked List input as follows: 1 -> 2-> 4 -> 5 -> 7 -> 8 -> 10-> 9  and you are given a k = 2, so the output should be 1 -> 10 -> 4 -> 5 -> 7 -> 8 -> 2 -> 9 so how do we achieve it??? Intuition The most brute force solution one can think of is using Array data structure. For that, we will traverse through linked List and store all the elements in the Array, swap the two numbers and again insert it in theLinked List again. Not bad, but let's deal with it, it is not the optimal solution and far from being as an acceptable solution in interviews. So what can we done instead of that??? Let's try to look deep into the working of Linked List first and how do we traverse it. Linked List is a linear data structure that...

Group Anagrams – Python Solution Explained

Problem Overview The Group Anagrams problem is a common challenge in coding interviews and competitive programming. The goal is to group a list of strings such that all anagrams are placed in the same group. Anagrams are words that contain the same characters but in different orders. For example, given the input ["eat", "tea", "tan", "ate", "nat", "bat"] , the expected output is [['eat', 'tea', 'ate'], ['tan', 'nat'], ['bat']] . Approach and Solution In this blog post, we'll discuss an efficient solution using Python's built-in data structures. The provided code uses a dictionary to group the anagrams. Here’s a step-by-step explanation of the approach: Code Breakdown Explanation Initialization: We use defaultdict from the collections module to create a dictionary ( hm ) where each key will map to a list of anagrams. This is useful because it automatically initializes ...
