Uncle Fang is walking along the edge of his farmland when he suddenly notices that a row of corn in the field is very unsightly.
There are $n$ corn plants in this row, and their heights are uneven.
Uncle Fang believes that a non-decreasing sequence is beautiful, so he decides to first increase the height of some corn plants, and then remove the corn plants that spoil the beauty, so that the heights of the remaining corn plants form a non-decreasing sequence.
Uncle Fang can choose an interval and increase the height of all corn plants in this interval by 1 unit. He can perform this operation at most $K$ times.
As for removing corn, he can choose any set of corn plants to remove.
What is the maximum number of corn plants that can remain to form a beautiful row of corn?
Input
The first line contains two integers $n$ and $K$, representing the number of corn plants in the row and the maximum number of operations that can be performed, respectively.
The second line contains $n$ integers, where the $i$-th integer represents the height $a_i$ of the $i$-th corn plant from left to right.
Output
Output a single integer, the maximum number of remaining corn plants.
