Interview Questionnaire 

4 Questions

  • Q1. 1. Mininum cost to reach the last cell of a 2D matrix. Required moves are only downward or to the right direction
  • Ans. 

    Minimum cost to reach last cell of 2D matrix with only downward or right moves.

    • Use dynamic programming approach to solve the problem.

    • Calculate minimum cost for each cell by considering minimum cost of its adjacent cells.

    • Final answer will be the minimum cost to reach the last cell.

  • Answered by AI
  • Q2. Design a Stack that can support getMin functionality. Whenever it calls getMin on stack it should return the min element in the stack.
  • Ans. 

    Design a stack that supports getMin functionality to return the minimum element in the stack.

    • Create two stacks, one for storing the actual elements and another for storing the minimum elements.

    • Push elements onto both stacks simultaneously.

    • When popping an element, pop from both stacks.

    • To get the minimum element, peek at the top of the minimum stack.

  • Q3. Design a TreeSet functionality
  • Ans. 

    TreeSet is a data structure that stores unique elements in sorted order.

    • TreeSet is implemented using a Red-Black tree

    • It provides O(log n) time complexity for basic operations like add, remove, and contains

    • It also provides methods like first(), last(), headSet(), tailSet(), and subSet()

    • TreeSet can be used to implement priority queues and sorting algorithms

  • Answered by AI
  • Q4. Design a ArrayList that supprorts all the existing funtions of a list plus getMax functionality also.
  • Ans. 

    Design an ArrayList with getMax functionality.

    • Create a custom ArrayList class that extends the existing ArrayList class.

    • Add a getMax() method that returns the maximum value in the list.

    • Override the add() method to keep track of the maximum value in the list.

    • Update the maximum value whenever an element is added or removed from the list.

Interview Preparation Tips

Round: Test
Experience: They did not expect any code in this round. An algo or pseudo code is fine.



1) You are given 2 vessels with capacity M liters and N liters capacity and infinite supply of water. You need to find the minimum number of steps required to get P liters. Any of the below action is considered a step



     a) Filling vessel with water



     b) Emptying vessel



     c) Pouring water from one vessel to another vessel.



2) Given n sets each containing m integers. You need to create MinDiff set by picking exactly 1 element from each set. The difference between the maximum and minimum elements in the MinDiff set should be minimum.



eg: for the sets {30, 20, 10, 40},{ 22, 33, 44, 99},{ 16, 17, 18, 19} min diff set is {19, 20, 22}. Max and min elements in MinDiff set are 22 and 19 and their difference is 3.

Round: Technical Interview
Experience: 1) you will be given the binary representation of the numbers in the form of 2D array.eg: r1- 00001

r2- 00100

r3- 01010

r4- 00110

r5- 00111 This means the elements are 1, 4, 10 , 6 and 7.

A number “n” is given. Let us say that n can be formed by doing bitwise OR operation on rows of given matrix. What is the minimum number of rows that needs to be deleted from the matrix so that “n” can never be formed by doing the OR of the rows.

If n is 14(01110) then it can be formed by doing r2|r3 or r3|r4. You can prevent n formation either by deleting {r2,r4} or {r3}. But {r3} has least number of elements so it is the required set.2) Find the average of mid 50% of elements in the running stream of integersI have not cleared round-II so no further questions.
