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

program main
    implicit none
    integer n
    integer n1, n10, n100,flag
    read(*,*) n
    
    n100 = (n - mod(n,100))/100
    n1 = mod((n - n100*100),10)
    n10 = (n - n100*100 - n1)/10

    flag = 0
    if(n100 == 7) then
        flag = 1
    end if

    if(n10 == 7) then
        flag = 1
    end if

    if(n1 == 7) then
        flag = 1
    end if

    if(flag == 1) then
        write(*,*) "Yes"
    else
        write(*,*) "No"
    end if

end program
