Polycarpus participates in a competition for hacking into a new secure messenger. He's almost won.input

Having carefully studied the interaction protocol, Polycarpus came to the conclusion that the secret key can be obtained if he properly cuts the public key of the application into two parts. The public key is a long integer which may consist of even a million digits!

Polycarpus needs to find such a way to cut the public key into two nonempty parts, that the first (left) part is divisible by a as a separate number, and the second (right) part is divisible by b as a separate number. Both parts should be positive integers that have no leading zeros. Polycarpus knows values a and b.

Help Polycarpus and find any suitable method to cut the public key.

Input

The first line of the input contains the public key of the messenger — an integer without leading zeroes, its length is in range from 1 to 106 digits. The second line contains a pair of space-separated positive integers a, b (1 ≤ a, b ≤ 108).

Output

In the first line print "YES" (without the quotes), if the method satisfying conditions above exists. In this case, next print two lines — the left and right parts after the cut. These two parts, being concatenated, must be exactly identical to the public key. The left part must be divisible by a, and the right part must be divisible by b. The two parts must be positive integers having no leading zeros. If there are several answers, print any of them.

If there is no answer, print in a single line "NO" (without the quotes).

題目大意:

給你一個長度不超過1000000的一個整數,讓你將其分紅兩個整數(固然不包含前導0咯),使得第一個數是a的倍數,第二個數是b的倍數。


思路:


一、暴力維護一個前綴模,再暴力維護一個後綴模。

二、而後枚舉每個點,若是其前綴模和後綴模都是0,並且第二個數不包含前導0的狀況出現,那麼就輸出YES。不然輸出NO
