N

Output

If N contains the digit 7, print Yes; otherwise, print No.

Sample Input 1

Sample Input 2

123

Sample Output 2

123 does not contain the digit 7.

Sample Input 3

777

Sample Output 3

Yes

Solution in Julia (1.4.0) (judge verdict: Wrong Answer)

x = 117
y=[0,0,0]

y[1] = x - (x % 100)
y[2] = (x - y[1]) - (x - y[1])%10
y[3] = x - y[1] - y[2]


if(y[1] == 700)
    println("Yes")
elseif(y[2] == 70)
    println("Yes")
elseif(y[3] == 7)
    println("Yes")
else
    println("No")
end
