def split_and_join(line):
    line = line.split()
    
    return "-".join(line)

if __name__ == '__main__':
    line = input()
    result = split_and_join(line)
    print(result)

def split_and_join(line): words = line.split(" ") result="-".join(words) return result

def split_and_join(line): words = line.split(" ") result="-".join(words) return result

if name == 'main': line = input() result = split_and_join(line) print(result)

return "-".join(line.split(" "))

That’s a clear example of how breaking down elements and rejoining them can simplify tasks, much like how well-structured PPC Strategies for Ecommerce break complex goals into manageable steps for better results.
