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: Wrong Answer)

a,b=map(int,input().split())

cnt=0
for i in range(1,10):
  for j in range(0,10):
    for k in range(0,10):
      num=int(str(i)+str(j)+str(k)+str(j)+str(i))
      if a<=num<=b:
        print(num)
        cnt+=1
        
print(cnt)
