Compile time polymorphism is achieved through method overloading, where multiple methods have the same name but different parameters.
Run time polymorphism is achieved through method overriding, where a subclass provides a specific implementation of a method that is already def...

Given a string, find the frequency of each character from 'a' to 'z' in the string.
Create an array of size 26 to store the frequency of each character from 'a' to 'z'.
Iterate through the string and increment the count of the corresponding character in the array.
Print the array of frequencies as the output for each test case.
You are given two strings 'A' and 'B'. While string 'A' is constant, you may apply any number of left shift operations to string 'B'.
Your task is to calcu...

This round started at 11 am and went till 3 pm.
Out of 120 students that appeared in online coding test, 20 were shortlisted for the first round of interviews.
In this round, everyone was asked some moderate level coding questions. We were supposed to write the code in our IDE, present the screen and show the interviewer the output of our code.
The interview started with the introduction being followed by 2 coding problems.

Find the length of the longest subarray with zero sum in an array of integers.
Iterate through the array and keep track of the running sum using a hashmap.
If the running sum is seen before, the subarray between the current index and the previous index with the same sum is a subarray with zero sum.
Update the length of the longest subarray with zero sum as you iterate through the array.
Example: For arr1 = [1, -1, 3, 2, -2...

7 students were shortlisted for the HR round. This round started at 7:30 pm and went till 8:30 pm.
Like all the other rounds, this round too was virtual (on google meet). In the beginning, the interviewer introduced himself and then asked questions based on my resume.
All the 7 candidates were selected in the HR round.
Tip 1 : Questions are asked on DSA, so practice questions and it is not the number of questions you practice, but how well you practice the questions. Prepare a notebook and write down the approach you follow. Make proper notes and maintain that notebook. Will help for quick revision.
Tip 2 : Conceptual questions are asked from topics other than DSA. So watching videos on youtube will not help. Read the book thoroughly to make yourself ready for interviews.
Tip 3 : ALWAYS read about the real-life examples of the concepts you read. This is often asked in interviews and you will definitely regret failing to answer this question.
Tip 1 : Having projects in resume will help you to give the direction to your interview, which increases the chances of selection.
Tip 2 : Add some achievements other than academics, it shows that you are a team player and increases the probability of getting shortlisted. BUT do not write anything that is not true or else, it will backfire.

To make the red fishes 98%, 50 fishes have to be removed from the aquarium.
Calculate 1% of 200 fishes to find the number of red fishes.
Subtract the number of red fishes from 200 to find the number of non-red fishes.
Calculate 2% of the total number of fishes to find the desired number of red fishes.
Subtract the desired number of red fishes from the current number of red fishes to find the number of fishes to be removed.
