1. Kitty, Perry and Terry. Kitty the kitten challenges her kittens, Perry and Terry, to the following game: run on the roofs of the houses on the street after their owners' house, Perry on the houses on the right side of the street, numbered with consecutive even numbers, and Terry on the left side where the houses are numbered with consecutive odd numbers. They are asked to tell Kitty how many of the houses have a number with a sum of digits that is a perfect square when they reach the end of the street.
Knowing the house number of their owners, n>0, and that all other houses have numbers greater than this, and knowing the house number at the end of the street, m with n<m, determine and display the numbers communicated to Kitty by Perry and Terry.

The numbers n and m, non-zero natural numbers with a maximum of 5 digits, will be read from the file case.in, and the result will be displayed in the file case.out.
