Problem Statement

You are given a three-digit positive integer N.

Determine whether N is a palindromic number.

Here, a palindromic number is an integer that reads the same backward as forward in decimal notation.

Constraints

100≤N≤999

N is an integer.

Input

Input is given from Standard Input in the following format:

N

Output

If N is a palindromic number, print Yes; otherwise, print No.

Sample Input 1

575

Sample Output 1

Yes

N=575 is also 575 when read backward, so it is a palindromic number. You should print Yes.

Sample Input 2

123

Sample Output 2

No

N=123 becomes 321 when read backward, so it is not a palindromic number. You should print No.

Sample Input 3

812

Sample Output 3

No

Solution in Python (3.4.3) (judge verdict: Runtime Error)

def gcd(a,b):
    #a=min(a,b)
    #b=max(a,b)
    while b:
        a,b= b, a%b
    return a

def lcm(a,b):
    return a*b//gcd(a,b)
T=[]
N=int(input())
for i in range(N):
    T.append(int(input()))

ans=1
for t in T:
    ans=lcm(ans, t)

print(ans)
