Reversed link...read more
Ans. 
Reverse a singly linked list of integers and return the head of the reversed linked list.
• Iterate through the linked list and reverse the pointers to point to the previous node instead of the next node.

• Use three pointers - prev, current, and next to reverse the linked list in O(N) time and O(1) space complexity.

• Update the head of the reversed linked list as the last node encountered during the reversal process.

Q2. 
Sort 0 1 2 Problem Statement
Given an integer array arr of size 'N' containing only 0s, 1s, and 2s, write an algorithm to sort the array.
Input:
The first line contains an integer 'T' representing the n...read more
Ans. 
Sort an array of 0s, 1s, and 2s in linear time complexity.
• Use three pointers to keep track of 0s, 1s, and 2s while traversing the array.

• Swap elements based on the values encountered to sort the array in-place.

• Time complexity should be O(N) and space complexity should be O(1).

Q1. Tell me difference between treemap and hashmap
Ans. 
HashMap is an unordered collection while TreeMap is a sorted collection based on keys.
• HashMap uses hashing to store key-value pairs, while TreeMap uses a red-black tree for sorting keys.

• HashMap allows one null key and multiple null values, while TreeMap does not allow null keys but allows null values.

• HashMap is generally faster for lookups and insertions, while TreeMap is useful when you need to iterate over keys in so
