93539 is an example of a palindrome (If one reads it from left to right or right to left, it is the same). From, 100-1000, how many of these exist? [I Love Maths]

Always been into palindromes... Goes back to first Z80 assembler program I wrote at college in 81 which was a palindrome analyser 🤣🤣🤣

Will watch mathematic replies with interest
