`It worked! The door is open!' Soren said with relief. `We only have to do something with this huge pile of coins. It blocks the way.'
`Let's not waste time and blow them up. All these coins are really starting to annoy me,' Alba replied.
`Well, it's quite dangerous. Don't forget that the coins are magic, so when you cast a spell to destroy them, each coin strikes back
with a shockwave of the same power as the spell. If we destroy k coins, the response will be k times stronger than our spell.
We can kill ourselves just by casting a spell that is too powerful. The only good thing
is that the shockwave energy has a bit different nature and will not cause new
explosions.'
`Seems like we'll have to choose the power of each spell very carefully.'
`It's not that difficult. Each coin has its resistance limit.
The Annihilation Spell destroys all the coins whose resistance limit is no greater than the power of the spell.
We'll just have to cast the spell several times, each time increasing the power, that's all.'
`And how many times do we have to hide from the shockwaves?'
`It doesn't really matter. We only need to remove as many coins as we can without killing ourselves.'
`Yeah, but we better try to cast as few spells as possible.'
`Sure.'
Input
The first line contains two integers: n is the number of coins and p is the
maximum shockwave power the wizards can survive (1 ≤ n ≤ 1000; 1 ≤ p ≤ 109).
The second line contains n integers ai, which are the resistance limits of the coins (1 ≤ ai ≤ 106).
Output
Output two integers separated with a space: the maximum amount of coins the wizards can destroy without killing themselves and the minimum
number of spells they have to cast the Annihilation Spell to destroy all these coins.
