Getting perfect squares, differently

+1

−0

Create a program that gets all perfect squares starting from 0 or 1 without using any methods of multiplication (repetitive addition) and exponentiation (repetitive multiplication). Output them for validation.

Things such as built-ins/functions related to these unusable methods can't be used either. pow(x,y) and x**y are examples of these unusable methods.

A simple, yet tricky activity! Being code-golf, the shortest program in each programming language wins!
