Problem Statement

Having learned the multiplication table, Takahashi can multiply two integers between 1 and 9 (inclusive) together.

Given an integer N, determine whether N can be represented as the product of two integers between 1 and 9. If it can, print Yes; if it cannot, print No.

Constraints

1 \leq N \leq 100

N is an integer.

Input

Input is given from Standard Input in the following format:

N

Output

If N can be represented as the product of two integers between 1 and 9 (inclusive), print Yes; if it cannot, print No.

Sample Input 1

10

Sample Output 1

Yes

10 can be represented as, for example, 2 \times 5.

Sample Input 2

50

Sample Output 2

No

50 cannot be represented as the product of two integers between 1 and 9.

Sample Input 3

81

Sample Output 3

Yes

Solution in Ruby (2.3.3) (judge verdict: Accepted)

# 入力文字を取得
input = gets

# Nを取得
N = input.to_i

# 計算用変数
count = 0
candidate = [1,2,3,4,5,6,7,8,9]

# Nを九九に含まれるか判定
candidate.each{|a|
    candidate.each{|b|
        c = a * b
        break if c == N
        count = count + 1
    }
}

# 結果を出力
if count == 81
    print 'No'
else 
    print 'Yes'
end
