# Print Number Star Right Triangle Pattern Type1

## PRINT PATTERN  1 2*3 4*5*6 7*8*9*10

For any input number N Print the following code – For below code N=4
```1
2*3
4*5*6
7*8*9*10```

### PREREQUISITE:

Basic knowledge in Java programming, usage of loops.

### ALGORITHM:

1. Take input from user i.e number of lines required (N value).
2. Take two loops one for each line (say ‘i’) and other for each digit in a particular line (say ‘j’). i starts from 1 and j starts from 1.
3. Take a result variable (say ‘a’) and initialize it with 1.
4. Here ‘i’ loop is used to access each line from 1 to n and ‘j’ loop is used to print values in each line. j loop is executed until it reaches i value.
5. Print ‘a’ value along with * and post increment  until the j loop reaches a value less than i.
6. Print the final value ‘a’ of each line and go to next line.
7. Repeat the ‘i’ loop until it reaches n.

### CODE IN JAVA:

Run
```import java.lang.*;
import java.io.*;
class Main
{
public static void main(String[] args)throws IOException
{
int n, i, j, a = 1;
System.out.print("Enter N value:");

for(i = 1; i <= n; i++)
{
for(j = 1; j < i; j++)
{
System.out.print((a++)+"*");
}
System.out.println(a++);
}
}
}
```
```Enter N value:5
1
2*3
4*5*6
7*8*9*10
11*12*13*14*15```
