K Subsets with Equal Sum Problem Statement
Determine whether it is possible to partition an array ARR into K subsets, each having an equal sum.
Example:
Input:
ARR = [3, 5, 2, 4, 4], K = 2
Output:
tru...
Yes, it is possible to partition an array into K subsets with equal sum.
Check if the total sum of the array is divisible by K.
Use backtracking to try all possible combinations of subsets.
Keep track of visited elements to avoid repetition.
Example: ARR = [3, 5, 2, 4, 4], K = 2. Possible subsets: [4, 5] and [2, 3, 4].
Keys in database management systems are unique identifiers for rows in a table.

Foreign key is a field in one table that refers to the primary key in another table.
Composite key is a combination of multiple columns that uniquely identify a record.
Unique key ensures that all values in a column are uni...
Sort a "K" Sorted Doubly Linked List Problem Statement
You are given a doubly linked list with 'N' nodes, where each node can deviate at most 'K' positions from its actual position in the sorted list. Your...
Sort a doubly linked list with nodes that can deviate at most K positions from their actual position in the sorted list.
Iterate through the doubly linked list and maintain a window of size K+1 to sort the elements within the window.
Use insertion sort within the window to sort the elements efficiently.
Repeat the process until the entire list is sorted.
Time complexity can be optimized to O(N*log(K)) using a priority...
Merge k Sorted Linked Lists
You are provided with 'K' sorted linked lists, each sorted in increasing order. Your task is to merge all these lists into one single sorted linked list and return the head of t...
Merge k sorted linked lists into one single sorted linked list.
Create a min-heap to store the heads of all k linked lists.
Pop the smallest element from the heap and add it to the result list.
If the popped element has a next element, push it back to the heap.
Repeat until the heap is empty and return the merged sorted list.
Maximum Meetings Problem Statement
Given the schedule of N meetings with their start time Start[i] and end time End[i], you need to determine which meetings can be organized in a single meeting room such t...
Given N meetings with start and end times, find the maximum number of meetings that can be organized in a single room without overlap.
Sort the meetings based on their end times.
Iterate through the sorted meetings and select the next meeting that does not overlap with the current meeting.
Keep track of the selected meetings and return their indices in the order they are organized.
