Encoding Process: gtk to Z3Rr

Step 1: Map ASCII Characters to Binary

ASCII CharacterBinary Value
g01100111
t01110100
k01101011

Step 2: Group Bits into 6-bit Chunks

The binary string is grouped into 6-bit chunks for Base64 encoding:

011001 110111 010001 101011

Step 3: Convert Binary to Base64

Binary ValueBase64 Character
011001Z
1101113
010001R
101011r

When combined, these characters form the encoded string: "Z3Rr"
