Gain insights into Java programming by exploring conditional statements, loops, math, logic, inheritance, generics, and arraylists, to become an intermediate Java developer.

Learn Java for free with this interactive course, and get a handle on one of the most popular programming languages in the world.

You'll start with a simple hello world program and proceed to cover common concepts such as Conditional Statements, Loop Statements, Math, and Logic in Java, before moving on to more advanced concepts like Inheritance, Generics, and ArrayLists, along with much more.

By the time you're done, you'll be an intermediate level Java developer, ready to take on your own projects.

# Problem statement
Implement a Java method that takes an *integer* size as input and **displays** a table that represents a [Pascal's triangle](https://en.wikipedia.org/wiki/Pascal%27s_triangle) using a *two-dimensional* array.  

## Function prototype
```java
void printPascalTri(int size)
```
## Sample input
```java
int size = 5;
```
## Sample output

*Print* Pascal's triangle of the size 5.<br>
Pascal's triangle is filled from the top towards the bottom. In *Pascal's triangle*: 

* **first** and the **second** *rows* are set to **1**. 
* Each *element* of the *triangle* (from the **third** row downward) is the **sum** of the element directly above it and the *element* to the **left** of the *element* directly **above** it. 


>**Note:** In order to move a value to the next line you can use `\n`.

## Pictorial representation
See the example *Pascal triangle*(**size=5**) below:
```java
1
1 1
1 2 1
1 3 3 1
1 4 6 4 1
```

In this challenge, you have to implement Pascal's triangle using a two-dimensional Array.
