Aptitude, technical MCQs and c/c++ questions of medium type

Q1. 1. Given offset, find the indices of multi dimensional array 2. Bitwise operations coding 3. Structure padding 4. Code memory storage
Ans. 
Technical questions related to programming concepts and memory management.
• To find indices of a multi-dimensional array using offset, divide the offset by the size of each element and use the quotient as the index for the first dimension. Repeat this process for each dimension.

• Bitwise operations are used to manipulate individual bits in a binary number. Examples include AND, OR, XOR, and bit shifting.

• Structure padding i...read more

Q2. Garbage Collection in Java SQL queries
Ans. 
Garbage collection in Java is an automatic process of freeing up memory by removing unused objects.
• Java uses a mark-and-sweep algorithm for garbage collection

• Objects that are no longer referenced by any part of the program are eligible for garbage collection

• System.gc() can be used to suggest garbage collection, but it is not guaranteed to run immediately

• Garbage collection can cause performance issues if not managed pro

Q2. OOP concepts with example code
Ans. 
OOP concepts involve encapsulation, inheritance, and polymorphism in object-oriented programming.
• Encapsulation: bundling data and methods that operate on the data into a single unit (class). Example: class Car { private String color; public void setColor(String c) { color = c; } }

• Inheritance: creating new classes based on existing classes, inheriting their attributes and methods. Example: class SUV extends Car { privat...read more

Ans. 
Modify a singly linked list by inserting a new node after every 'K' nodes with the sum of previous 'K' nodes.
• Traverse the linked list while keeping track of 'K' nodes at a time

• Calculate the sum of the 'K' nodes and insert a new node with the sum after every 'K' nodes

• Handle the case where the number of remaining nodes is less than 'K' by inserting a node with the sum of remaining nodes

• Update the pointers accordingly to

Ans. 
Calculate the Nth Fibonacci number efficiently using dynamic programming.
• Use dynamic programming to store previously calculated Fibonacci numbers to avoid redundant calculations.

• Start with base cases F(1) and F(2) as 1, then iterate to calculate subsequent Fibonacci numbers.

• Return the Nth Fibonacci number as the final result.
