Solution in Fortran (GNU Fortran 9.2.1) (judge verdict: Accepted)

      program lucky7
      implicit none
      integer N,A(3)
      read(*,*) N
      A(0)=N/100
      A(1)=(N-A(0)*100)/10
      A(2)=N-A(0)*100-A(1)*10
      if(A(0)==7.or.A(1)==7.or.A(2)==7) then
         write(*,*) "Yes"
      else 
         write(*,*) "No"
      end if
      stop 
      end program lucky7
