10+ Aequs Interview Questions and Answers

Arrays store elements in contiguous memory locations, while LinkedLists store elements in nodes with pointers to the next element.

• Arrays have constant time access to elements using index, while LinkedLists have O(n) access time as they need to traverse from the beginning.

• Arrays have fixed size, while LinkedLists can dynamically grow and shrink in size.

• Arrays are better for random access and search operations, while LinkedLists are better for insertions and deletions in the mi...read more

Use a hashmap to store frequency of each number in the array for efficient retrieval of maximum occurring number.

• Use a hashmap to store the frequency of each number in the array.

• Iterate through the array and update the frequency count in the hashmap.

• Find the number with the highest frequency in the hashmap to get the maximum occurring number.

No, Function Overloading is not the only example of Compile Time Polymorphism.

• Function Templates are another example of Compile Time Polymorphism where a single function can operate on different data types.

• Operator Overloading is also an example of Compile Time Polymorphism where operators can be overloaded to work with different data types.

• Static Polymorphism achieved through method overloading is another example of Compile Time Polymorphism.

Answering questions related to LinkedList operations and Circular LinkedList.

• LinkedList Class: Implement a class with nodes containing data and a reference to the next node.

• Insertion: Add a new node at the beginning, end, or at a specific position in the LinkedList.

• Deletion: Remove a node by updating references to skip over it.

• Reversing: Traverse the LinkedList and reverse the links between nodes.

• Sorting: Implement a sorting algorithm like bubble sort or merge sort on the Lin...read more

Multi-Threading in Java allows multiple threads to execute concurrently. Generics in Java enable type-safe collections and classes.

• Multi-Threading in Java allows for concurrent execution of multiple threads.

• Generics in Java enable type-safe collections and classes by allowing the use of parameterized types.

• Example of Multi-Threading: creating a new thread using the Thread class and implementing the run() method.

• Example of Generics: defining a generic class like ArrayList to s...read more

Use recursion to reverse the string without using loops or other data structures.

• Create a recursive function that takes the string as input.

• In the function, check if the string is empty or has only one character, return the string in that case.

• Otherwise, call the function recursively with the substring excluding the first character and concatenate the first character at the end.

Pillars of OOP are Inheritance, Encapsulation, Abstraction, and Polymorphism. Real life example: Vehicles.

• Inheritance: Car and Bike classes inheriting from Vehicle class.

• Encapsulation: Data hiding in a class to protect it from outside interference.

• Abstraction: Using a remote control to operate a TV without knowing its internal workings.

• Polymorphism: Overloading a method with different parameters in a class.
