Implementing Pascal's Triangle

# Introduction

In this challenge, we will be implementing Pascal's Triangle using Java programming. Pascal's Triangle is a mathematical pattern that visualizes coefficients of binomials and reflects properties of combinations. The goal is to output and sum the first 10 rows of Pascal's Triangle using the knowledge of methods, one-dimensional arrays, two-dimensional arrays, and objects. We will use two source files, `YhTangle.java` and `TestYhTangle.java`, to write the code and validate the implementation.
