# Program to Print Pattern 13

Program to Print Pattern 13 on fibonacci, factorial, prime, armstrong, swap, reverse, search, sort, stack, queue, array, linkedlist, tree, graph, pattern, string etc.

## Program to print the following pattern

1 2 3 4 5
1 2 3 4
1 2 3
1 2
1

### 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 6.
5. Repeat step 6 to 8 until all value parsed.
6. Set i = n and check i>0;
7. Set j = 1 and check j <= i;
8. Print j values.
9. End

### JAVA

```public class Pattern7
{
public static void main(String[] args)
{   int i ,j;
int n = 5;
for(i = n; i>0 ; i-- )
{
for(j = 1; j<=i ; j++)
{
System.out.print(j);
}
System.out.println("");
}
}
}
```

### Python

```for i in range(1,6):
for j in range(1, 6-i+1):
print(str(j)+" "),
print("")
```

### C Program

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

### C# program

```using System;
public class Program
{
public static void Main(string[] args)
{
for (int i = 5; i >= 1; --i)
{
for (int j = 1; j <= i; ++j)
{
Console.Write(j);
}
Console.WriteLine();
}
}
}
```

### PHP program

```<?php
for (\$i = 5; \$i >= 1; \$i--)
{
for (\$j = 1; \$j <= \$i ; \$j++)
{
echo \$j;
}
echo "</br>";
}
?>
```
