Problem Statement

Given eight integers

S1,S2,…, and S8, print Yes if they satisfy all of the following three conditions, and No otherwise.

The sequence (S1,S2,…,S8) is monotonically non-decreasing. In other words,

S1≤S2≤?≤S8.S1,S2,…, and S8 are all between 100 and 675, inclusive.

S1,S2,…, and S8 are all multiples of 25.

Constraints 0≤Si ≤1000

All input values are integers.

Input

The input is given from Standard Input in the following format:

S1 S2 … S8

Output

Print the answer.

Sample Input 1

125 175 250 300 400 525 600 650

Sample Output 1

Yes

They satisfy all of the three conditions.

Sample Input 2

100 250 300 400 325 575 625 675

Sample Output 2

No

They violate the first condition because

S4>S5.

Sample Input 3

0 23 24 145 301 413 631 632

Sample Output 3

No

They violate the second and third conditions.
