Given a linked list where each node has two pointers: the first points to the next node in the list, and the second is a random pointer that can point to any node ...
Create a deep copy of a linked list with random pointers without using references of original nodes.
Iterate through the original linked list and create a new node for each node in the list.
Store the mapping of original nodes to new nodes in a hashmap to handle random pointers.
Update the random pointers of new nodes based on the mapping stored in the hashmap.
Return the head of the copied linked list.

Determine the maximum amount of money a thief can steal from houses without looting two consecutive houses.
Create an array 'dp' to store the maximum money that can be stolen from each house without looting two consecutive houses.
Iterate through the houses and update 'dp' based on the maximum money that can be stolen from the current house.
Return the maximum value in 'dp' as the answer.

str in C is a data type used to represent strings as arrays of characters.
str in C is typically declared as an array of characters, terminated by a null character '\0'.
Functions like strcpy(), strcmp(), and strlen() are commonly used with str in C.
Example: char str[10] = "hello"; // Declaration of a string in C
Pointers in C are variables that store memory addresses of other variables.
Pointers are used to access and manipulate memory directly.
They are denoted by an asterisk (*) before the variable name.
Example: int *ptr; // declares a pointer to an integer variable

Use a hash set to find duplicates in an array of strings.
Create a hash set to store unique elements.
Iterate through the array and check if the element is already in the hash set.
If it is, then it is a duplicate. If not, add it to the hash set.
Find the single duplicate element in an array of strings with length n-1.
Iterate through the array and use a HashSet to keep track of elements seen so far.
If an element is already in the HashSet, that is the duplicate element.
Return the duplicate element once found.

Implement Merge Sort algorithm to sort a sequence of numbers in non-descending order.
Divide the input array into two halves recursively
Sort the two halves separately
Merge the sorted halves to produce a fully sorted array
Time complexity of Merge Sort is O(n log n)

Given an N * N maze with binary values, find and print all possible paths for a rat to reach the destination cell.
Use backtracking to explore all possible paths from the starting cell to the destination cell.
At each cell, check if it is a valid move (within bounds and not blocked), then recursively explore all four directions.
Keep track of the path taken so far and mark the cells accordingly.
Once the destination cell i...
