**Exercise: Computing 1's and 2's Complements**

**Objective:** Learn how to calculate 16-bit 1's and 2's complements of binary numbers.

**Problem Statement:**  
Determine the 16-bit 1’s and 2’s complements for the following binary numbers:

a. 10000  
b. 100111100001001  
c. 0100111000100100

**Instructions:**

1. **1's Complement:** Flip each bit of the binary number, changing all 0s to 1s, and all 1s to 0s.
2. **2's Complement:** Take the 1's complement of the binary number, then add 1 to the least significant bit (rightmost bit).

**Example Calculation:**  
Let's calculate the 1's and 2's complement for option (a):

- **Original Binary Number:** 0000 0000 0001 0000 (padded with leading zeros for 16 bits)
- **1's Complement:** 1111 1111 1110 1111
- **2's Complement:** 1111 1111 1111 0000 (Add 1 to the 1's complement)

Now, apply these steps to the other options and check your results.
