Four or one Some natural numbers want to become 1 or 4 and will evolve infinite times if they have to, to become what they want to. To evolve, they use a function F such that N = F(N). Function F(N) is defined as : F(N)=sum_of_digits(N2) So, your task is that given a number N, output if it is possible for it to ultimately become {1 or 4} or not. Input First line contains T which is the number
