Journey
In the beginning, I started learning about basics DSA concepts. These included topics like array, string, stack, queue and solving questions on hacker rank. After practicing enough on Hacker Rank, I moved to advanced DSA topics including Linked List, Tree, Graph, DP, etc. I practiced these topics on Geeksforgeeks, leetcode, codeforces. Then I gave some mock interviews as well that helped me prepare for interviews.
Application story
Shortlisting was done on the basis of resumes and then further interview rounds were carried out. Off campus and we directly applied through their portal.

My basic concepts of all the topics were clear and I also prepared HR questions through mock interviews. I practised all the basic to medium coding question before interview.

1. Anagram Pairs
Moderate

0/80
Asked in companies
You are given two strings 'str1' and 'str1'.
You have to tell whether these strings form an anagram pair or not.
The strings form an anagram pair if the letters of one string can be rearranged to form another string.
Pre-requisites:
Anagrams are defined as words or names that can be formed by rearranging the letters of another word. Such as "spar" can be formed by rearranging letters of "rasp". Hence, "spar" and "rasp" are anagrams.
Other examples include:
'triangle' and 'integral'
'listen' and 'silent'
Note:
Since it is a binary problem, there is no partial marking. Marks will only be awarded if you get all the test cases correct.
Problem approach
Two strings are called anagrams if they accommodate a similar group of characters in a varied sequence.
To check if two strings are anagrams, the below steps are followed:
Initialize two strings in two variables.
Check if the length of the two strings is similar, if not then the strings are not an anagram.
If the result is true, take the two strings and store them in a character array.
Sort the two character arrays, then check if the two sorted arrays are alike.
If the result is true, the two strings are anagram else, not anagram.
2. Middle Of Linked List

Asked in companies
Given a singly linked list of 'N' nodes. The objective is to determine the middle node of a singly linked list. However, if the list has an even number of nodes, we return the second middle node.
Note:
1. If the list is empty, the function immediately returns None because there is no middle node to find.
2. If the list has only one node, then the only node in the list is trivially the middle node, and the function returns that node.
