Problem Statement

Find the number of palindromic numbers among the integers between A and B (inclusive).
Here, a palindromic number is a positive integer whose string representation in base 10 (without leading zeros) reads the same forward and backward.

Constraints

10000 \leq A \leq B \leq 99999

All input values are integers.

Input

Input is given from Standard Input in the following format:

A B

Output

Print the number of palindromic numbers among the integers between A and B (inclusive).

Sample Input 1

11009 11332

Sample Output 1

4

There are four integers that satisfy the conditions: 11011, 11111, 11211 and 11311.

Sample Input 2

31415 92653

Sample Output 2

612

Solution in Python (3.4.3) (judge verdict: Runtime Error)

a,b=input().split()
a=str(int(a)-1)
def f(x):
  c=int(x[0])
  d=int(x[1])
  m=(c-1)*100+d*10
  e=int(x[2])
  g=int(x[4])*10+int(x[5])
  if g<d*10+c:
    m+=e
  else:
    m=m+e+1
  return m
print(f(b)-f(a))
