Sets are unordered collections of unique elements while lists are ordered collections of elements.
Sets do not allow duplicate elements while lists do.
Sets do not maintain the insertion order while lists do.
Sets have faster lookup time for specific elements while lists have faster iteration time.
Examples of sets in Java include HashSet and TreeSet while examples of lists include ArrayList and LinkedList.
Finally block is used to execute code after try-catch block, regardless of whether an exception is thrown or not.
Finally block is optional and follows the catch block.
It is used to clean up resources like closing files, database connections, etc.
Finally block is executed even if an exception is not caught.
It is used to ensure that a certain piece of code is always executed.
Example: try { //code } catch (Exception e) { ...

The N Queens Problem involves finding all possible placements of N queens on an N x N chessboard without threatening each other.
Use backtracking algorithm to explore all possible configurations.
Keep track of rows, columns, and diagonals to ensure queens do not threaten each other.
Generate all valid configurations and print them out.
Given an integer array arr
of size 'N' containing only 0s, 1s, and 2s, write an algorithm to sort the array.
The first line contains an integer 'T' representing the n...
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).

Reverse words in a string while handling leading, trailing, and multiple spaces.
Split the input string by spaces to get individual words
Reverse the order of the words
Join the reversed words with a single space in between
You are provided with the head of a linked list containing integers. Your task is to determine if the linked list is circular.
Detect if a given linked list is circular by checking if it forms a closed loop.
Traverse the linked list using two pointers, one moving at double the speed of the other.
If the two pointers meet at any point, the linked list is circular.
If the faster pointer reaches the end of the list (NULL), the linked list is not circular.
