how many integers from 101 to 600 , inclusive , remains the value unchanged when the digits were reversed ?
"question is asking for palindrome first digit possibilities - 1 through 5 = 5 6 is not possible here because it would result in a number greater than 6 ( i . e 606 , 616 . . ) second digit possibilities - 0 though 9 = 10 third digit is same as first digit = > total possible number meeting the given conditions = 5 * 10 = 50 answer is a ."
divide(const_100.0, const_10)
