Ans.

Develop a program to compute the factorial of a given integer 'n'.

Create a function to calculate factorial using a loop or recursion
Handle edge cases such as negative input or input exceeding constraints
Return 'Error' if factorial is undefined
Example: For input 5, output should be 120

Q2. Angle Calculation Between Clock Hands

Given a specific time in hours and minutes, your task is to calculate the smallest possible angle between the hour hand and the minute hand of a clock.

Input:

T = ...read more

Ans.

Calculate the smallest angle between the hour and minute hands of a clock for a given time.

Calculate the angles of the hour and minute hands based on the input time.
Find the absolute difference between the angles of the hour and minute hands.
Return the smaller angle between the two possible angles.
Ensure to handle cases where the smaller angle is greater than 180 degrees.

Q3. Java Garbage Collector functioning

Ans.

Java Garbage Collector automatically manages memory allocation and deallocation.

Garbage Collector runs in the background and frees up memory by removing objects that are no longer in use.
It uses different algorithms like Mark and Sweep, Copying, and Generational to manage memory.
