A SDE-2 was asked 3mo ago
Q. Design a data structure that supports the following two operations: void addNum(int num) - Add a integer number from the data stream to the data structure. double findMedian() - Return the median of all ele...
Ans. 

Efficiently finding the median from a stream of integers requires maintaining a balanced data structure for dynamic data.

  • Use Two Heaps: Maintain a max-heap for the lower half and a min-heap for the upper half of the numbers to efficiently find the median.

  • Insertion: When a new number is added, decide which heap to insert it into based on its value relative to the current medians.

  • Balancing Heaps: After each insertio...

Q. What is a copy constructor?
Ans. 

A copy constructor creates a new object as a copy of an existing object, ensuring proper resource management.

  • A copy constructor is a special constructor in C++ that initializes an object using another object of the same class.

  • Syntax: ClassName(const ClassName &obj) { /* copy data */ }

  • Used for deep copying when an object contains pointers to dynamically allocated memory.

  • Example: If class A has a pointer, the co...

Q. How would you sort an array based on a user-defined order?
Ans. 

Sort an array of strings based on a user-defined order.

  • Define the custom order as a string, e.g., 'cba'.

  • Create a mapping of characters to their indices for quick lookup.

  • Use a sorting function that utilizes the mapping to sort the array.

  • Example: For array ['a', 'b', 'c'] and order 'cba', the result should be ['c', 'b', 'a'].

A Software Engineer Intern was asked 3mo ago
Q. How do you allocate memory for a vector?
Ans. 

Allocating memory for a vector involves reserving space for its elements to optimize performance and avoid reallocations.

  • Use `std::vector<Type> vec;` to declare a vector.

  • To allocate memory, use `vec.reserve(size);` to set capacity without changing size.

  • Example: `vec.reserve(10);` reserves space for 10 elements.

  • To initialize with a specific size, use `std::vector<Type> vec(size);`.

  • Example: `std::vector&...

Q. What is the concept of a virtual table?
Ans. 

A virtual table is a mechanism used in object-oriented programming to support dynamic method resolution for polymorphism.

  • Virtual tables (vtables) store pointers to virtual functions of a class.

  • Each class with virtual functions has its own vtable.

  • When an object is created, it holds a pointer to its class's vtable.

  • Example: In C++, if class A has a virtual function, derived class B can override it, and the vtable wil...

      I appeared for an interview in Mar 2025, where I was asked the following questions.

      • Q1. Inheritancebased question, virtual function 2 times called
      • Q2. Sort and array in user defined order
      • Ans. 

        Sort an array of strings based on a user-defined order.

        • Define the custom order as a string, e.g., 'cba'.

        • Create a mapping of characters to their indices for quick lookup.

        • Use a sorting function that utilizes the mapping to sort the array.

        • Example: For array ['a', 'b', 'c'] and order 'cba', the result should be ['c', 'b', 'a'].

      • Q3. Median from stream of integers
      • Ans. 

        Efficiently finding the median from a stream of integers requires maintaining a balanced data structure for dynamic data.

        • Use Two Heaps: Maintain a max-heap for the lower half and a min-heap for the upper half of the numbers to efficiently find the median.

        • Insertion: When a new number is added, decide which heap to insert it into based on its value relative to the current medians.

        • Balancing Heaps: After each insertion, en...

      • Q4. Smart Pointer and all types
      • Q5. Copy contructor
      • Ans. 

        A copy constructor creates a new object as a copy of an existing object, ensuring proper resource management.

        • A copy constructor is a special constructor in C++ that initializes an object using another object of the same class.

        • Syntax: ClassName(const ClassName &obj) { /* copy data */ }

        • Used for deep copying when an object contains pointers to dynamically allocated memory.

        • Example: If class A has a pointer, the copy co...

      • Q6. Shallow and deep copy
      • Q7. Tree taversals all types
      • Ans. 

        Tree traversals are methods for visiting all nodes in a tree data structure, including pre-order, in-order, post-order, and level-order.

        • Pre-order Traversal: Visit root, then left subtree, then right subtree. Example: For tree (A, B, C), output is A, B, C.

        • In-order Traversal: Visit left subtree, then root, then right subtree. Example: For tree (A, B, C), output is B, A, C.

        • Post-order Traversal: Visit left subtree, then ri...

      Why are women still asked such personal questions in interview?
      I recently went for an interview… and honestly, m still trying to process what just happened. Instead of being asked about my skills, experience, or how I could add value to the company… the questions took a totally unexpected turn. The interviewer started asking things like When are you getting married? Are you engaged? And m sure, if I had said I was married, the next question would’ve been How long have you been married? What does my personal life have to do with the job m applying for? This is where I felt the gender discrimination hit hard. These types of questions are so casually thrown at women during interviews but are they ever asked to men? No one asks male candidates if they’re planning a wedding or how old their kids are. So why is it okay to ask women? Can we please stop normalising this kind of behaviour in interviews? Our careers shouldn’t be judged by our relationship status. Period.
