Reviewer's Guide by Sourcery

This PR introduces two new Java classes: one for checking palindrome numbers and another for printing matrix diagonals. The palindrome checker implements LeetCode question #9 using a straightforward digit reversal approach, while the matrix diagonal printer uses nested loops to traverse and print diagonal elements.

issue (bug_risk): Potential integer overflow when reversing numbers close to Integer.MAX_VALUE.

Consider adding overflow detection or using long to handle larger numbers safely.
