Tip

Tip 1 : Begin early, but do not regret your timing.
Tip 2 : Be consistent. Do something everyday. Small progress every single day is better than no a rushed, hard-work day and then nothing for a week

First round took place at around 10:15 AM. It was a online round. The interviewer was very sweet, and he asked me if i knew about the problems before

1. Next smaller Palindrome
Easy

0/40

#### You are given a number 'N' in the form of a string 'S', which is a palindrome. You need to find the greatest number strictly less than 'N' which is also a palindrome.

2. Explain how heaps are implemented

Explain how heaps are implemented

Problem approach

Step 1: Heaps require the property of sorting themselves such that the smallest or largest element is at the top. So we need something that can sort itself in reasonable time complexity every-time a new element is added or deleted. A good way to get that is a binary search tree which can do this in O(log n).

3. Diamond Problem

Diamond problem is when more than one class inherits a class and one class inherits those classes. Ex. Classes B and C inherit class A, and class D inherits classes B and C. If B and C have the same function and class D calls that function, then there will be an error as the compiler won't know which class's function to call.

Problem approach

Either use scope-resolution operator or virtual functions

4. What are destructors
Problem approach

A destructor is a member function that is invoked automatically when the object goes out of scope or is explicitly destroyed by a call to delete . A destructor has the same name as the class, preceded by a tilde ( ~ ). For example, the destructor for class String is declared: ~String()

Problem approach

Sorted it using recursion, wherein the current element (top) is taken out and the function called by recursion to sort the remaining stack. Then the element is inserted in its right place.
