As a token of his gratitude, Takahashi has decided to give his mother an integer sequence. The sequence A needs to satisfy the conditions below:    * A consists of integers between X and Y (inclusive).   * For each 1\leq i \leq |A|-1, A_{i+1} is a multiple of A_i and strictly greater than A_i.  Find the maximum possible length of the sequence.
import math
x,y = map(int,input().split())
print(int(math.log2(y/x)))
x,y = map(int,input().split())
s=0
while x<=y:
  s += 1
  y //= 2
print(s)
