Questions asked by the interviewer:
1. Probability (Medium level)
2. Coding Problem (Easy) (Tips:- first give some brute force approach then move forward to optimized approach)
3. Questions from your projects that you mentioned in your resume.
1. Puzzle
3 Ants and Triangle
Problem approach
Collision doesn’t happen only in following two cases :
1) All ants move in counterclockwise direction.
2) All ants move in clockwise direction.
Since every ant has two choices (pick either of two edges going through the corner on which ant is initially sitting), there are total 23 possibilities.
Out of 23 possibilities, only 2 don’t cause collision. So, the probability of collision is 6/8 or 3/4 and the probability of non-collision is 2/8 or 1/4.
2. Longest Palindromic Substring

Asked in companies
You are given a string ('STR') of length 'N'. Find the longest palindromic substring. If there is more than one palindromic substring with the maximum length, return the one with the smaller start index.
Note:
A substring is a contiguous segment of a string.
For example : The longest palindromic substring of "ababc" is "aba", since "aba" is a palindrome and it is the longest substring of length 3 which is a palindrome, there is another palindromic substring of length 3 is "bab" since "aba" starting index is less than "bab", so "aba" is the answer.
Problem approach
Step 1:- First I read the problem carefully
Step 2:- Then I wrote the code(Brute Force method)
Step 3:- Interviewer asked me to optimize the solution.
Step 4:- Then I gave the optimized solution(there is a simple logic behind the problem)
Here's your problem of the day
