Mainly mcqs and some coding questions
Calculate the Nth term in the Fibonacci sequence, where the sequence is defined as follows: F(n) = F(n-1) + F(n-2)
, with initial conditions F(1) = F(2) = 1
.
Calculate the Nth Fibonacci number efficiently using dynamic programming.
Use dynamic programming to store previously calculated Fibonacci numbers to avoid redundant calculations.
Start with base cases F(1) and F(2) as 1, then iterate to calculate subsequent Fibonacci numbers.
Optimize the solution to have a time complexity of O(N) by storing and reusing calculated values.

Check if a given string is a palindrome considering only alphanumeric characters.
Remove non-alphanumeric characters from the input string before checking for palindrome.
Use two pointers approach to compare characters from start and end of the string.
Convert all characters to lowercase for case-insensitive comparison.
Return true if the string is a palindrome, false otherwise.

Create a program for string manipulation using an array of strings.
Use built-in string manipulation functions like substring, replace, and concat.
Iterate through the array of strings to perform different manipulations.
Consider edge cases like empty strings or null values.
Example: Reverse each string in the array and concatenate them together.
HashMap is a data structure that stores key-value pairs and uses hashing to efficiently retrieve values.
HashMap internally uses an array of linked lists to store key-value pairs.
When a key-value pair is added, the key is hashed to determine the index in the array where it will be stored.
If multiple keys hash to the same index, a linked list is used to handle collisions.
To retrieve a value, the key is hashed again to fi...
