Q2. Merge two sorted Array Linkedlist delete a node
Ans. 
The question asks to merge two sorted arrays and delete a node in a linked list.
• To merge two sorted arrays, we can use a two-pointer approach.

• To delete a node in a linked list, we need to update the pointers of the previous and next nodes.

• Example: Merge [1, 3, 5] and [2, 4, 6] to get [1, 2, 3, 4, 5, 6].

• Example: Delete node with value 3 from linked list [1, 2, 3, 4, 5] to get [1, 2, 4, 5].

Q3. String is palindrome or not with recursion
Ans.

• If they are equal, recursively check the substring without the first and last characters.

• Continue this process until the string is empty or only has one character.

• If all comparisons are equal, the string is a palindrome.
