Q2. Find the voltage through the resistor
Ans. 
To find the voltage through a resistor, use Ohm's Law: V = I * R
• Use Ohm's Law: V = I * R, where V is the voltage, I is the current flowing through the resistor, and R is the resistance of the resistor

• If the current flowing through the resistor is 2A and the resistance is 5 ohms, the voltage would be V = 2 * 5 = 10V

• Make sure to use the correct units for current (Amps) and resistance (Ohms) to get the voltage in Volts

Q5. Explain the working of a capacitor and resistor and relation between resistance and length , area
Ans. 
Capacitors store electrical energy while resistors limit the flow of current. Resistance is directly proportional to length and inversely proportional to area.
• Capacitors store electrical energy by creating an electric field between two conductive plates separated by an insulating material

• Resistors limit the flow of current in a circuit by dissipating energy in the form of heat

• The resistance of a resistor is directly pr...read more

Q1. What do you know about Bill of Materials
Ans. 
Bill of Materials (BOM) is a comprehensive list of raw materials, components, and assemblies required to build a product.
• BOM is used in manufacturing to ensure all necessary materials are available for production.

• It includes details such as part numbers, quantities, and descriptions of each item.

• BOM can be hierarchical, with sub-assemblies listed under main assemblies.

• It helps in cost estimation, inventory management, ...read more

Q2. Access modifiers in java
Ans. 
Access modifiers in Java control the visibility of classes, methods, and variables.
• There are four types of access modifiers in Java: public, protected, default (no modifier), and private.

• Public: accessible from any other class.

• Protected: accessible within the same package or subclasses.

• Default: accessible only within the same package.

• Private: accessible only within the same class.

• Example: public class MyClass {}

Q3. Complete code of all projects
Ans. 
It is not common practice to provide complete code of all projects in an interview setting.
• It is not recommended to share complete code of all projects due to confidentiality and intellectual property concerns.

• Instead, focus on discussing the technologies used, challenges faced, and solutions implemented in your projects.

• Provide code snippets or high-level overviews of your projects to showcase your skills and experien

Q1. 
Team Formation Problem Statement
You will be provided with an array/list 'ARR' consisting of 'N' positive integers representing runs scored by 'N' top players in their last innings. An integer 'X' is also...read more
Ans. Brute Force
The basic idea of this approach is to iterate the whole ‘ARR’ from start and check for all the elements present after it. If the sum of the current pair is less than or equal to ‘X’ minus 30 then we will check if it is less than our temporary answer or not. If it is less then we will replace it with a temporary answer.
 
Here is the algorithm:
 
1. Declare a temporary array/list variable ‘ANS’ in which we...read more
