Journey
The interview process consisted of several rounds, each with unique challenges that tested my skills and knowledge. I would like to share my experience with you to help you prepare for your upcoming interviews. The first round was a subjective MCQ round, which tested my basic knowledge of programming languages, data structures, algorithms, and software engineering concepts. It was a challenging round, but I was able to answer most of the questions correctly. I recommend brushing up on your fundamentals before the interview to ensure success in this round. The second round was a coding round where I was given a coding problem to solve within a specified time limit. I was able to solve the problem, and the interviewer was impressed with my coding skills and the algorithm I used to solve the problem. To prepare for this round, I recommend practicing coding problems and data structures before the interview. In the interview round, I was asked several questions about my experience in software engineering, my knowledge of programming languages, and my approach to problem-solving. The interviewer was impressed with my responses and asked me some challenging questions related to software engineering concepts and algorithms. I was able to answer them satisfactorily and received positive feedback from the interviewer.

Ninja and his friend are playing a game in which his friend picks N opening brackets ‘(‘ and N closing brackets ‘)’. He then mixes all of them randomly and generates a string 'BRACKETS'. He asks Ninja to balance ‘BRACKETS’.

Example:
Here are some examples of balanced BRACKETS "(())", "()()", "(())()".

Ninja can perform the following operation to balance BRACKETS. In one operation, Ninja can pick two adjacent brackets and swap them. His friend challenges him to accomplish the task in minimum possible operations. Ninja needs your help to do this.

Can you help Ninja to make the string ‘BRACKETS’ balanced in minimum possible swaps?

Given two integers ‘Left’ and ‘Right’. Your task is to find the total count of ‘megaprime’ numbers from the range ‘Left’ to ‘Right’. A ‘megaprime’ number is a prime number and its individual digits are also prime.

For example, ‘53’ is a ‘megaprime’ number because ‘53’ is a prime number and its individual digits,‘3’ and ‘5’, are also prime. ‘13’ is not a ‘megaprime’ number because out of its individual digits (1, 3), ‘1’ is not prime.

Note :

1.’Left’ and ‘Right’ both are inclusive in the range ‘Left’ to ‘Right’.

Example :

‘Left’ = ‘23’  and ‘Right’ = ‘37’

binary_heap

All prime numbers from ‘23’ to ‘37’ are 23, 29, 31, 37

23 is ‘megaprime’ number because ‘2’ and ‘3’ both are prime
29 is not ‘megaprime’ number because ‘9’ is not a prime
31 is not a ‘megaprime’ number because ‘1’ is not a prime number
37 is ‘megaprime’ number because ‘3’ and ‘7’ both are prime numbers
Hence there are two ‘megaprime’ numbers 23, 37 out of 23, 29, 31, 37.

You are given an integer ‘N’. Your task is to find all palindromic numbers from 1 to ‘N’.

Palindromic integers are those integers that read the same backward or forwards.

Note:
Order of numbers should be in the non-decreasing matter.
For example:
You are given ‘N’ as 12, so the output should be [1, 2, 3, 4, 5, 6, 7, 8, 9, 11], as all single-digit numbers are palindromic, and 11 is also a palindromic number.
