The MCQ round consisted of a total of 30 questions and the domain of questions revolved around Java. There was no negative marking and the time given to each student to complete the MCQ round was 30 minutes, which means everyone had a minute for each question. Talking about the difficulty of this round then I would personally recommend going through the given below topics thoroughly :
OOPS concepts (Data Abstraction, Encapsulation, Inheritance, Polymorphism)
Basic Java constructs like loops and data types.

You are given two strings S and X containing random characters. Your task is to find the smallest substring in S which contains all the characters present in X.
Example:
Let S = “abdd” and X = “bd”.
The windows in S which contain all the characters in X are: 'abdd', 'abd', 'bdd', 'bd'.
Out of these, the smallest substring in S which contains all the characters present in X is 'bd'.
All the other substring have a length larger than 'bd'.

Note :
Try to solve the problem in 'Single Scan'. ' Single Scan' refers to iterating over the array/list just once or to put it in other words, you will be visiting each element in the array/list just once.
