package know;
public class Test1 {
public static void main(String [] args){
final int Row = 6;
int yh[][] = new int[Row][Row];
for (int i = 0; i yh[i][0] = 1;
yh[i][i] = 1;
} for (int i = 2; i for (int j = 1; j yh[i][j] = yh[i - 1][j - 1] + yh[i - 1][j];
} } for (int i = 0; i for(int k=Row-i;k>1;k--){
System.out.print( );
} for (int j = 0; j
