Java program to print the following pattern

Pattern:

             1
           1   1
         1   2   1
       1   3   3   1
     1   4   6   4   1
   1   5  10  10   5   1

In this example here we will have to print the above given pattern on console with the help of a Java program.

Algorithm:

Step 1:START.
Step 2:SET coe=1, rows= 6.
Step 3:SET i=0. REPEAT STEP 4 to STEP 11 UNTIL i<rows.< li=""></rows.<>
Step 4:SET space = 1. REPEAT STEP 5 and STEP 6 UNTIL space<(rows ?i).
Step 5:PRINT "".
Step 6:++space.
Step 7:SET j=0. REPEAT STEP 8 to STEP 9 UNTIL j<=i .
Step 8:IF(j==0||i==0)
SET coe=1
ELSE
SET coe=coe*(i-j+1) /j
PRINT coe.
Step 9:SET j = j+1.
Step 10:PRINT a new line.
Step 11:SET i=i+1.
Step 12:END.

Program:


class Main 
{
	public static void main(String[] args)  
	{  
	int coe=1,rows = 6;  
		for(int i = 0; i < rows; i++) 
		{  
			for(int space = 1; space < rows - i; ++space) 
			{  
			System.out.print("  ");  
			}  
			for(int j = 0; j <= i; j++) 
			{  
			if (j == 0 || i == 0)  
			coe = 1;  
			else  
			coe = coe * (i - j + 1) / j;  
			System.out.printf("%4d", coe);  
			}  
			System.out.println();  
		}  
	}  
}

Output:

             1
           1   1
         1   2   1
       1   3   3   1
     1   4   6   4   1
   1   5  10  10   5   1
