Question

The following steps can be used to encode a string of text using Base64 encoding:

1. Convert the ASCII characters to their corresponding decimal value
2. Convert the decimal values to their 8-bit equivalents
3. Join all of the bits together to form one continuous string
4. Split the combined string into groups of 6 bits
5. From left to right, convert each group of 6 bits to their corresponding decimal values
6. Convert those decimal values back to the corresponding Base64 values
If I started with the three ASCII characters "CSP", how many Base64 values will I be left with at the end?

Answer 1

The given steps outline the process of encoding a string of text using Base64 encoding. You will be left with 4 Base64 values: 'Q', '1', 'N', 'Q'.

Step-by-step explanation:

The given steps outline the process of encoding a string of text using Base64 encoding.

1. Convert the ASCII characters 'C', 'S', and 'P' to their decimal values: 'C': 67, 'S': 83, 'P': 80.
2. Convert the decimal values to their 8-bit equivalents: 'C': 01000011, 'S': 01010011, 'P': 01010000.
3. Join all the bits together to form one continuous string: '010000110101001101010000'.
4. Split the combined string into groups of 6 bits: '010000', '110101', '001101', '010000'.
5. Convert each group of 6 bits to their decimal values: '16', '53', '13', '16'.
6. Convert the decimal values back to the corresponding Base64 values: 'Q', '1', 'N', 'Q'.

You will be left with 4 Base64 values: 'Q', '1', 'N', 'Q'.
