INNER REDUCING PATTERN

Consider the following I/O samples.


SAMPLE INPUT: 4

SAMPLE INPUT: 4 4 4 4 4 4 4 

                            4 3 3 3 3 3 4 

                            4 3 2 2 2 3 4 

                            4 3 2 1 2 3 4 

                            4 3 2 2 2 3 4 

                            4 3 3 3 3 3 4 

                            4 4 4 4 4 4 4


C PROGRAM:
  
#include <stdio.h>
int min(int m,int n,int o,int p);
int min(int m,int n,int o,int p)
{
    int min1=m>n?n:m;
    int min2=o>p?p:o;
    return min1>min2?min2:min1;
}

int main()
{
    int n,i,j,x;
    scanf("%d",&n);
    for(i=0;i<(n*2)-1;i++,printf("\n"))
    {
        for(j=0;j<(n*2)-1;j++)
        {
            x=(min(i,j,((n*2-2)-i),((n*2-2)-j)));
            printf("%d ",(n-x));
        }
    }
    return 0;

}


OUTPUT:


 




 
The given source code in C program is short and simple to understand. The source code is well tested in DEV-C++ and is completely error free.
