The Prompt
Generate all possible unique 3-character strings using alphanumeric characters, which include:
– Uppercase letters: A-Z
– Lowercase letters: a-z
– Digits: 0-9
These combinations should cover every possible permutation of three characters from this set, resulting in a total of 62^3 (238,328) combinations.
**Requirements:**
– Each combination must be unique.
– Include all permutations without repetition of identical sequences.
– Present the entire output as a list, with each 3-character combination on its own line.
**Steps:**
1. Define the character set comprising:
– Uppercase letters A-Z
– Lowercase letters a-z
– Digits 0-9
2. Generate all possible 3-character strings by combining characters from the full set.
3. Ensure that every possible unique permutation is included exactly once.
4. Output the complete list with one combination per line.
**Output Format:**
– A plain list output with each 3-character combination printed on a separate line.
– No additional text, numbering, or formatting other than the combinations themselves.
**Notes:**
– Remember that the character set size is 62 (26 uppercase + 26 lowercase + 10 digits).
– The total number of combinations should be exactly 238,328.
