Hello,

I'm not sure if this is what you're looking for, but here is a solution in Python 2.7.5

It's not the most efficient solution xD But it worked for the sample problem

n=int(raw_input())

ab=[]

num=""
answers=[]


for i in xrange(n):
	ab.append(map(int, raw_input().split()))

for i in ab:
	ans=0
	for j in xrange(i[0],i[1]+1):
		num=str(j)[::-1]
		if(i[0] <= int(num) <= i[1]):
			ans+=1
	answers.append(ans)

blah=0

for i in answers:
	answernumber+=1
	print "Case "+str(answernumber)+": "+str(answers[answernumber-1])

Did you solve it? I did if you still asking for help
