Problem approach

The logic is simple.

Step1 : First, you take input from the user asking the value of n.

Step2 : Then you run a loop finding all the prime numbers.

Step3 :  Whenever a prime number is found, the count is increased and if the count is equal to the input of user (i.e., if the prime number found is the nth prime number), then print it.

Problem approach

1. We will take each word after a space “ “ in a sentence and pass it to a function.

2.The function transforms the characters of words in lowercase.

3. Now start traversing from the first character of the word and compare word[0] with word[length-1], word[1] with word[length-2] and so on.

4. If any mismatch occurs break loop else return true.

After the introduction he asked me some questions related to OOPS such as:
1. What are the principles of OOPS
2. What do you mean by polymorphism?
3. What is function overloading?
4. What are abstract classes and interface.

Then he gave me one coding question to solve. He told me to write the code on notepad and share screen.
question asked: Reverse the stack using recursion.

I was not able to solve this problem hence he gave me another question:
