#include<string.h>

int main()

{

    char str[50],srev[50];

    int l,mid,i,k=0,m,p,b,j;

    printf("Enter a Name : ");

    gets(str);

    l=strlen(str);

    m=l-1;

    if(l%2==1)

    {

        mid=(l/2);

        for(i=mid;i<l;i++)

        {

            srev[k]=str[i];

            k=k+1;

        }

        for(i=0;i<mid;i++)

        {

            srev[k]=str[i];

            k=k+1;

        }

        //puts(srev);

        for(i=0;i<l;i++)

        {

             b=0;

             for(j=0;j<l;j++)

             {

                  if(j>=m)

                  {

                          printf("%c",srev[b]);

                          b=b+1;

                  }

                  else

                  {

                          printf(" ");

                  }

             }

             printf("\n");

             m=m-1;
