Singleton ensures a class has only one instance, while Abstract Factory provides an interface for creating families of related objects.
Singleton pattern restricts the instantiation of a class to one object, ensuring there is only one instance of the class.
Abstract Factory pattern provides an interface to create families of related or dependent objects without specifying their concrete classes.

Detect loop in a linked list.
Use two pointers, slow and fast, to traverse the list.
If there is a loop, the fast pointer will eventually catch up to the slow pointer.
If the fast pointer reaches the end of the list, there is no loop.
Use parseInt() function to convert string to integer without ASCII conversion.
Use parseInt() function with radix parameter to specify the base of the number system
If radix is not specified, parseInt() will try to determine the base automatically
If the string contains non-numeric characters, parseInt() will return NaN

It was an online MCQ's + coding round consisting of 20 MCQ’s and 1 coding problem.
Check for a loop in a linked list by using two pointers moving at different speeds.
Use two pointers, one moving at double the speed of the other.
If there is a loop, the two pointers will eventually meet at the same node.
Example: 1 -> 2 -> 3 -> 4 -> 5 -> 2 (loop back to 2), the two pointers will meet at node 2.

The interview started at 8:30 pm in cc of Delhi Technological University itself and it was quite late. There was only a single interviewer and he asked me one coding question related to overflow of integers.
To check for integer overflow when multiplying two integers, use the properties of integer overflow and check if the result is within the valid range of the integer type.
Check if the signs of the two integers are the same to avoid overflow in case of multiplication.
Use the properties of integer overflow to detect if the result exceeds the maximum or minimum value of the integer type.
Consider using a larger data type or...

It was quite late . There was only one interviewer and I was asked about my family , education and future plannings and few questions related joining locations and documents etc.
Focus on data structures and algorithms part more. Tell the interviewer , starting from the brute force approach to the most optimal solution as this will give a good impression to the interviewer.
Application resume tips for other job seekersTo be honest, the problem-solving ability is the only thing that most companies care about. So you can manipulate your resume according to that. Mention your competitive programming handles in your resume and also other coding ranks or achievements which you have achieved.
