Sparse table is a data structure used to efficiently answer range queries on an array.

• Sparse table is used to optimize range query operations on an array.

• It precomputes and stores the answers to all possible range queries in a table.

• The table is constructed using a divide-and-conquer approach.

• Sparse table reduces the time complexity of range queries from O(n) to O(1).

• It is commonly used in scenarios where range queries are frequent and array elements are static.

Dijkstra's algorithm will not work when there are negative edge weights in the graph.

• Dijkstra's algorithm assumes that all edge weights are non-negative.

• If there are negative edge weights, the algorithm may produce incorrect shortest paths.

• In such cases, other algorithms like Bellman-Ford or Floyd-Warshall should be used.

• For example, consider a graph with a negative weight cycle.

Deleting the Kth node in a linked list.

• Traverse the linked list to the Kth node.

• Update the previous node's next pointer to skip the Kth node.

• Free the memory allocated to the Kth node.

• Handle edge cases such as deleting the head or tail node.

Minimum number of swaps required to make a given array of strings a palindrome.

• Create a hash table to store the frequency of each character in the array.

• Iterate through the array and count the number of characters with odd frequency.

• If the count is greater than 1, the array cannot be rearranged into a palindrome.

• Otherwise, use two pointers to swap characters and count the number of swaps required to make the array a palindrome.
