# Program to Print Pattern 17

Program to Print Pattern 17 on fibonacci, factorial, prime, armstrong, swap, reverse, search, sort, stack, queue, array, linkedlist, tree, graph, pattern, string etc.

## Program to print the following pattern

### Algorithm

1. Start
2. Let i be an integer number.
3. Let j be an integer number.
4. Let n be a integer number and initialize by 1.
5. Repeat step 6 to 9 until all value parsed.
6. Set i = 0 and check i<6;
7. Set j = 1 and check j <= i;
8. Print number n.
9. Then n++;
10. End

In this program, we are creating a right-angled triangle of numbers in increasing order. We are creating two loops, and 2nd loop is executing according to the first loop, inside 2nd loop printing the number row-wise i loop times.

### JAVA

```package programs;
public class pattern13
{
public static void main(String[] args)
{
int n=1;
for(int i=0;i<6;i++)
{
for(int j=1;j<i;j++)
{
System.out.print(" "+n);
n++;
}
System.out.println("");
}
}
}
```

### Python

```n = 5
k=1
for i in range(1,n):
for j in range(0,i):
print(k),
k=k+1
print("")
```

### C program

```#include <stdio.h>
int main()
{
int size = 5,n=1;
for (int i = size; i != 0; i--)
{
for (int j = 0; j<size-i; j++)
{
printf("%d",n);
n++;
}
printf("\n");
}
return 0;
}
```

### C# program

```using System;
public class Program
{
public static void Main(string[] args)
{
int i, j, rows, k = 1;
Console.Write("\n\n");
rows = 4;
for (i = 1; i <= rows; i++)
{
for (j = 1; j <= i; j++)
Console.Write("{0} ", k++);
Console.Write("\n");
}
}
}
```

### PHP program

```<?php
\$rows = 5;
\$n = 1;
for(\$i = \$rows; \$i != 0; \$i--)
{
for(\$space = 0; \$space < \$rows - \$i; ++\$space)
{
echo \$n;
\$n++;
}
echo "<br>";
}
?>
```
