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 are diodes and semiconductor
Ans. 
Diodes are electronic components that allow current to flow in one direction only, while semiconductors are materials with conductivity between that of insulators and conductors.
• Diodes are used in rectifiers to convert AC to DC power

• Semiconductors are used in electronic devices like transistors and integrated circuits

• Diodes have a forward voltage drop, typically around 0.7V for silicon diodes

• Semiconductors have a band
