- Q1. Find the palindrome in the string?
- Ans.
To find palindromes in a string, compare characters from both ends towards the middle.
Iterate through each string in the array
Check if the string is equal to its reverse to determine if it's a palindrome
Examples: 'level', 'radar', 'madam'
- Q2. Difference between linked list and array?
- Ans.
Arrays store elements in contiguous memory locations, while linked lists store elements in nodes with pointers to the next node.
Arrays have fixed size, while linked lists can dynamically grow or shrink.
Accessing elements in arrays is faster (O(1)), while in linked lists it is slower (O(n)).
Inserting or deleting elements in arrays can be inefficient, while in linked lists it is efficient.
Example: Array - [1, 2, 3, 4], L

Interview Questionnaire

- Q1. What are different exceptions?
- Ans.
Exceptions are errors that occur during program execution and can be handled using try-catch blocks.
Checked exceptions: must be handled or declared in the method signature
Unchecked exceptions: occur at runtime and do not need to be declared
Error: serious problems that cannot be handled, such as OutOfMemoryError
Examples: NullPointerException, ArrayIndexOutOfBoundsException
- Q2. How to handle exceptions?
- Ans.
Exceptions should be handled gracefully to prevent application crashes.
Use try-catch blocks to catch exceptions.
Handle exceptions at the appropriate level of abstraction.
Log exceptions to aid in debugging.
Provide meaningful error messages to the user.
Avoid catching generic exceptions.
Use finally blocks to release resources.
Consider using custom exceptions for specific error conditions.
- Q3. How to create custom List which is read-only?
- Ans.
To create a custom read-only list, use the ReadOnlyCollection class in C#.
Create a List
object with the desired elements. Use the AsReadOnly() method to create a read-only wrapper around the list.
Use the ReadOnlyCollection
class to create a truly read-only list. Example: List
myList = new List {"apple", "banana", "orange"}; Example: var readOnlyList = myList.AsReadOnly();
Example: var trulyReadOnlyList = new ReadOnlyCollect
- Q4. What are different collections?
- Ans.
Collections are data structures that store and manipulate groups of related objects.
Collections are used to store and manipulate groups of related objects
They can be classified into three main categories: Lists, Sets, and Maps
Lists maintain the order of elements and allow duplicates (e.g. ArrayList, LinkedList)
Sets do not allow duplicates and do not maintain order (e.g. HashSet, TreeSet)
Maps store key-value pairs and d...
- Q5. Write code for binary search
- Ans.
Binary search is a search algorithm that finds the position of a target value within a sorted array.
The array must be sorted before applying binary search
Compare the target value with the middle element of the array
If the target value is smaller, search the left half of the array
If the target value is larger, search the right half of the array
Repeat until the target value is found or the search space is exhausted
