Problem

f(x) = 1st digit of x + 2nd digit of x + ... + last digit of x

f(7) = 7
f(55) = 10
f(100) = 1
f(20192019201920192019) = 60

for all 10 lines, print f(x), repeat f(y) on the same line until no change separated by spaces

7: 7
55: 10 1
99999999999: 99 18 9

PS. \n at the end of all 10 lines because I am very nice :)
