Code Golf Challenge

• Write a program that counts down from 10 (and can either end at 0|1) -- your choice
• Prints one number per line
• Can optionally accept a command-line argument
• No looping constructs are allowed, such a for and while
• Make it as short as possible, but still readable
• Please reply with your own solutions, include the programming language
• • Include instructions on how to compile && run

countdown.c

#include <stdio.h> // compile & run: gcc -Wall countdown.c -o countdown && ./countdown
int n = 10; int main(int argc, char *argv[]) { printf("%d\n", n) && --n && main(n, NULL); }

countdown.py

import sys # run: python3 countdown.py 10
def main(n:int): sys.stdout.write(f"{n}\n") and n-1 and main(n-1)
main(int(sys.argv[1]))

countdown.sh

# run ./countdown.sh 10
echo $1 && (($1-1)) && $0 $(($1-1))
