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.
X,Y = (int(_) for _ in input().split())



cnt = 1 
progression_num = X

while progression_num > Y:
    progression_num *= 2
    if progression_num > Y:
        break
    cnt += 1

print(cnt)

X,Y = (int(_) for _ in input().split())



cnt = 1 
progression_num = X

while progression_num <= Y:
    progression_num *= 2
    if progression_num > Y:
        break
    cnt += 1

print(cnt)
