What Is  Recursion?

Recursion is a process of repeating itself in a similar way. if a function call itself inside the same function, then it is called a recursive calling of a function.
Recursion means a  function is called itself the same function, it is known as recursion in C++.

What Is GCD?

GCD(Greatest Common Divisor) or HCF (Highest Common Factor) . When  we finding the factor of two numbers, Highest Common Factor of  numbers is the Largest factor that divides these two numbers.

What Is Natural  Number?

Simply all the counting numbers {…-3,-2-1,0,1, 2, 3, …} are commonly called natural numbers.

Natural numbers As such, it is a whole, non-negative are all number 1, 2, 3, 4,5,6,7,8,9,10… They are usually counting  number and they will continue to infinity.while Whole number are all natural numbers including 0.

Here  the inner loop creates the  space and the second inner loop computes the value of binomial coefficient, creates indentation space and prints the binomial coefficient for that particular column.

Let see the concept of creating a pascal triangle in step-by-step .

1 – Take value for number of rows to be printed in rows.
2 – Outer loop  runs for n times to print rows.
3 – Inner loop run for j to (rows – 1)
4 – That will print blank space ” “.
5 – ending the inner loop.
6 – Than another loop iterate form  j to i.
7 – Where we check condition=>
if (j == 0 || i == 0)
coef = 1
else
coef = coef*(i-j+1)/j.
8 – in each loop if condition satisfied we will print  coefficient value till the total number of rows.

The program output is come  out as shown.
