TASK 3
The Persian mathematician Al-Karaji (953-1029) computed the first description of Pascal's triangle given below.
It was later repeated by the Persian poet-astronomer-mathematician Omar Khayyám (1048-1131); thus the
triangle is also referred to as the Khayyam triangle in Iran.

The Pascal's triangle determines the coefficients which arise in binomial expressions. For example, consider the
expansion
(x + y)? = x² + 2xy + y = 1x³y® + 2x'y' + 1x®y?.
The coefficients of the terms are in the third row of the triangle. As a general approach, In general, when x + y is
raised to a positive integer power we have:
(x + y)" = aox" + ax-ly + azx"-?y² + ... + an-1xy-1 + any",
where the coefficients a; in this expansion are precisely the numbers on row (n+1) of Pascal's triangle. Each row
of the triangle can be computed by adding the pairs of numbers in the previous row from left to right. Write,
Compile and Execute a Java program that prints the Pascal's triangle given above.
