Mouser Electronics Associate Interview Questions and Answers

2 problem was given to solve
1) Smallest Negative balance - -----%20America%20-%20Weekly%20Algorithm%20Challenges/Week%2021%20Algorithm%20Challenge/Smallest%20Negative%20Balance.md
2) Find the absolute difference between alpha & beta from the array.
Alpha -An element k in a array occurs k consecutive time
Beta - An element k in an array occurs k consecutive time starting from index k

Sample input
Arr[] = {2,2,2,4,4,4,4,1,2,2]
Output
Alpha - 3
Beta - 1
Absolute difference - 1

Note : consider array index starts with 1

This round is classified as easy to medium.

Q1. How the current is flowed in the semiconductor
Ans. 
Current flows in a semiconductor due to the movement of charge carriers, either electrons or holes.
• Current flows in a semiconductor when charge carriers (electrons or holes) move under the influence of an applied electric field.

• In an n-type semiconductor, current is carried by electrons, while in a p-type semiconductor, current is carried by holes.

• The flow of current can be controlled by applying a voltage across the s...read more

Q2. OOP concepts with example code
Ans. 
OOP concepts involve encapsulation, inheritance, and polymorphism in object-oriented programming.
• Encapsulation: bundling data and methods that operate on the data into a single unit (class). Example: class Car { private String color; public void setColor(String c) { color = c; } }

• Inheritance: creating new classes based on existing classes, inheriting their attributes and methods. Example: class SUV extends Car { privat...read more

Q2. Garbage Collection in Java SQL queries
Ans. 
Garbage collection in Java is an automatic process of freeing up memory by removing unused objects.
• Java uses a mark-and-sweep algorithm for garbage collection

• Objects that are no longer referenced by any part of the program are eligible for garbage collection

• System.gc() can be used to suggest garbage collection, but it is not guaranteed to run immediately

• Garbage collection can cause performance issues if not managed pro

Round difficulty - Easy

The Technical interview was held on Zoom and the interview lasts for 1 hour. All the questions were from the skills mentioned in the resume.
Firstly interviewer asked me to give a self-introduction, later asked for a brief explanation of the projects and way of working.
Later series of questions were related to academics.
 

Q1. Add K Nodes
You are given a Singly Linked List of integers and an integer 'K'.
Your task is to modify the linked list by inserting a new node after every 'K' node in the linked list with ...read more
Ans. Naive approach
• We will iterate through the linked list and store the sum of the nodes in a variable 'CURR_SUM' (initialized as zero) and keep a check of the number of nodes traversed since the last insertion with a variable 'NODES_TRAVERSED' (also, initialized as zero).
• As we traverse the list, we add the value to the 'CURR_SUM' and increment the value of 'NODES_TRAVERSED'.
• When the value of 'NODES_TRAVERSED'becomes equal...read more

Q2. Nth Fibonacci Number
Nth term of Fibonacci series F(n), where F(n) is a function, is calculated using the following formula -
    F(n) = F(n-1) + F(n-2), 
    Where, F(1) = F(2) = 1
Provided N you have...read more
Ans. Recursive Approach
• In this approach, we use recursion and uses a basic condition that :
  • If ‘N’ is smaller than ‘1’(N<=1) we return ‘N’
  • Else we call the function again as ninjaJasoos(N-1) + ninjaJasoos(N-2).
• In this way, we reached our answer.
Space Complexity: O(n)Explanation:
O(N),  where ‘N’ is the given number.  
As recursion uses a stack of size ‘N’
