Fusu's Battle Judgment

Fusu has become the chief strategist of the Star War Earth Fleet, but she is not very smart.

The artificial intelligence has computed that if Fusu always answers NO, the probability of her judgment being completely correct in a campaign is \(x\%\). On the other hand, if she always answers YES, the probability is \(y\%\).

Note that \(x + y \neq 100\) necessarily, because there is also the case where she needs to answer both YES and NO, but that probability is not important. Since she is not smart, she can only choose one of the two strategies: always answer YES or always answer NO.

Fusu wants to make her judgment as accurate as possible. Therefore, if the probability when answering NO is higher than when answering YES, she will always answer NO; if the probability when answering YES is higher, she will always answer YES.

If both strategies provide the same probability of being correct, output equal probability.

inputFormat

The first and only line contains two integers \(x\) and \(y\) separated by a space, where \(x\) represents the probability (in percent) of being correct if Fusu always answers NO, and \(y\) represents the probability if she always answers YES.

outputFormat

Output a single line containing either YES, NO, or equal probability based on the strategy Fusu should choose. Output YES if \(y > x\), NO if \(x > y\), or equal probability if \(x = y\).
