Java program to print number star square pattern type 2

Print Number Star Square Pattern Type 2

In this java program we’re going to make number star pattern type-2 . Take input from user i.e number of lines required (N value).Take two loops one for each line (say ‘i’) and other for each digit in a particular line (say ‘j’). i starts from n and j starts from 1.Take a result variable (say ‘a’) and initialize it with (i*(i-1))+1, Since each line starts with 13,9,5,1.Here ‘i’ loop is used to access each line from N to 1 and ‘j’ loop is used to print values in each line. For example in line 2 the value of i=3 and for contents in second line (i.e 9*10*11*12) the value for j for digit 9 is j=1 and for digit 10 is j=2.Print ‘a’ value along with * and post decrement  until the j loop reaches a value less than n.Print the final value ‘a’ of each line.Repeat the ‘i’ loop until it reaches 1. Algorithm

• Take input from user i.e number of lines required (N value).
• Take two loops one for each line (say ‘i’) and other for each digit in a particular line (say ‘j’). i starts from n and j starts from 1.
• Take a result variable (say ‘a’) and initialize it with (i*(i-1))+1, Since each line starts with 13,9,5,1.
• Here ‘i’ loop is used to access each line from N to 1 and ‘j’ loop is used to print values in each line. For example in line 2 the value of i=3 and for contents in second line (i.e 9*10*11*12) the value for j for digit 9 is j=1 and for digit 10 is j=2.
• Print ‘a’ value along with * and post decrement  until the j loop reaches a value less than n.
• Print the final value ‘a’ of each line.
• Repeat the ‘i’ loop until it reaches 1.
