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 (3.8.2) (judge verdict: Accepted)

A,B=map(int,input().split())
N = 0
res = 0
def checkPali(n):
  # n = 100*a + 10*b +c
  c = n%10
  a = n//10000
  b = (n - 10000*a)//1000
  d = (n - c)/10
  e = d%10
  if a == c and b == e:
    return True
  else:
    return False
for i in range(B-A+1):
  N = A + i
  if checkPali(N):
    res+=1
print(res)
