Bhaskara's lemma, named after the Indian mathematician Bhaskara II, provides a useful technique for finding integer solutions to certain types of Diophantine equations. Specifically, it relates to finding integer solutions for the equation of the form: \\\[ x^2 - dy^2 = N \\\] where \\(d\\) is a non-square positive integer, and \\(N\\) is a given integer.
