Q1. 1. Find the smallestMissingNumber in given array using Bitwise OR operation alone 2. Based on Array data Manipulation.
Ans. 
Using Bitwise OR operation to find the smallest missing number in an array.
• Iterate through the array and perform Bitwise OR operation with each element to set corresponding bit in a bitmask

• Iterate through the bitmask to find the first unset bit, which represents the smallest missing number

• Example: Array [0, 1, 3, 4, 6] would have a bitmask of 10101, smallest missing number is 2

Q1. What is electrice current?
Ans. 
Electric current is the flow of electric charge through a conductor.
• Electric current is measured in amperes (A)

• It is caused by the movement of electrons

• Direct current (DC) flows in one direction while alternating current (AC) changes direction periodically

• Electric current is used to power electrical devices such as lights, motors, and computers
