## Logic to print given pattern

Before I discuss the logic to print the given pattern I recommend you to have a careful eye on to the pattern. Following observations can be made about the pattern.

1. It contains of N rows (where N is the total rows to be printed).
2. Each row contains exactly double column as in previous row. And the first row contains 1 column.
3. As per each column contains an integer from 1 to 9 in increasing order. When the number count reaches 10 it restarts to 1.

Below is the program that converts the above logic to computer code to print the given pattern.

## Program to print the given pattern

``````/**
* C program to print the given number pattern
*/

#include <stdio.h>

int main()
{
int i, j, N, colCount, value;

colCount = 1;
value = 1;

printf("Enter rows: ");
scanf("%d", &N);

for(i=1; i<=N; i++)
{
for(j=1; j<=colCount; j++)
{
if(value == 10)
value = 1; // Restart at 10

printf("%d ", value);

value++;
}

printf("\n");

// Increase the total number of columns by 2
colCount *= 2;
}

return 0;
}``````

Output

```Enter rows: 5
1
2 3
4 5 6 7
8 9 1 2 3 4 5 6
7 8 9 1 2 3 4 5 6 7 8 9 1 2 3 4```
