    Merge Two Sorted Arrays Problem Statement

    Given two sorted integer arrays ARR1 and ARR2 of size M and N, respectively, merge them into ARR1 as one sorted array. Assume that ARR1 has a size of M + N to hol...

  • Ans. 

    A simple approach would be to create a new arrays with size as sum of the sizes of both the arrays. Copy the elements of both the arrays in the new array and sort the array. 
    A space optimised approach also exists. While traversing the two sorted arrays parallelly, if we encounter the jth second array element is smaller than ith first array element, then jth element is to be included and replace some kth element in...

    Reverse a Stack Using Recursion

    You are given a stack of integers. Your task is to reverse the stack using recursion without using any extra space other than the internal stack space used due to recursion...

  • Ans. 

    Recursion can be used to reverse a stack. In this approach, we pop the top element from the given stack and recursively call another instance of the same function. When this child function returns to the parent function, append the popped element to the bottom of the stack. For this, two recursive functions can be used: reverseStack() and insertAtBottom().

    It checks if the stack is empty or not. Th...

  • Q1. What is the JVM?
  • Ans.

  • Q2. How are objects created and managed in JVM memory?
  • Ans. 

    When you use a new keyword, the JVM creates an instance for the object in a heap. While the reference of that object stores in the stack. There exists only one heap for each running JVM process. When heap becomes full, the garbage is collected.

  • Q3. What is polymorphism in Java?
  • Ans. 

    Polymorphism in Java is a concept by which we can perform a single action in different ways. Polymorphism is derived from 2 Greek words: poly and morphs. The word "poly" means many and "morphs" means forms. So polymorphism means many forms.

    There are two types of polymorphism in Java: compile-time polymorphism and runtime polymorphism. We can perform polymorphism in java by method overloading and method overriding.
