The task does not require us to read any input – it is a creative problem. We only have to output any non‑empty string that consists of printable ASCII characters (codes 32 … 126).
No special format or further processing is needed.
So the whole program can simply print one such character and finish.
Algorithm
print "a"
(Any other printable ASCII character would also be valid.)
We must show that the algorithm always outputs a string that satisfies the problem statement.
The algorithm prints exactly one character, namely `'a'`. `'a'` is a printable ASCII character because its code (97) lies in the range 32 … 126. The output string contains at least one character, hence it is not empty.
Thus the produced output meets all requirements of the problem statement, so the algorithm is correct. ∎
Complexity Analysis
The algorithm performs a single constant‑time print operation.
Time complexity: O(1)
Space complexity: O(1) (only the output buffer is used)
Reference Implementation (Python 3)
import sys
def solve() -> None: """ Print a non‑empty string. The content of the string can be anything; here we simply use 'Hello'. """
Any non‑empty string will do; choose something short and clear.
sys.stdout.write("Hello")
if name == "__main__": solve()
The program follows exactly the algorithm proven correct above and conforms to the required function signature `solve()`.
