how many integers from 101 to 900 , inclusive , remains the value unchanged when the digits were reversed ?
"question is asking for palindrome first digit possibilities - 1 through 8 = 8 9 is not possible here because it would result in a number greater than 9 ( i . e 909 , 919 . . ) second digit possibilities - 0 though 9 = 10 third digit is same as first digit = > total possible number meeting the given conditions = 8 * 10 = 80 answer is d ."
divide(900, const_10)
