I was interviewed in Oct 2021.
Round duration - 60 Minutes
Round difficulty - Hard
Given an integer N, determine and print all the prime numbers between 2 and N, inclusive.
Integer N
Prime numbers printed on separate lines
Generate and print all prime numbers between 2 and N, inclusive.
Iterate from 2 to N and check if each number is prime
A prime number is only divisible by 1 and itself
Print each prime number on a new line

Given two strings 'STR' and 'PTR', identify all starting indices of 'PTR' anagram substrings in 'STR'. Two strings are anagrams if one can be rearranged to form the other.
Implement a function to find all starting indices of anagram substrings of a given string in another string.
Create a frequency map of characters in the 'PTR' string.
Use a sliding window approach to check for anagrams in 'STR'.
Return the starting indices of anagram substrings found.
Example: For input 'BACDGABCD' and 'ABCD', output should be [0, 5].

Oops concepts and 1 DSA problem
You are provided with a string, termed as DIGIT_PATTERN
, which consists solely of digits. The objective is to identify the first digit that repeats in the sequence. If there's no...
Identify the first repeating digit in a given string of digits.
Iterate through the string and keep track of seen digits using a set.
Return the first digit that repeats, or -1 if no digit repeats.
Time complexity: O(n), where n is the length of the input string.
Round duration - 60 Minutes
Round difficulty - Medium
Firstly Some general questions and then suddenly a cosing question with modifications
Given an input string STR
, generate and print all possible permutations of the string.
str
All permutations of the input string, each on a new line.
Generate and print all possible permutations of a given input string.
Use recursion to generate all permutations by swapping characters in the string.
Maintain a visited array to keep track of characters already used in a particular permutation.
Print each permutation as it is generated.
Handle duplicate characters by skipping swapping if the character is already in the current position.
Tip 1 : You should be perfect in what you know
Tip 2 : Prepare atleast DSA standard questions very well
Tip 3 : Don't ignore OOPs, they are asked very frequently.
Tip 1 : Add good projects
Tip 2 : Must mention all your coding profiles and github where you worked.
