杨晖三角形：
1
1 1
1 2 1
1 3 3 1
1 4 6 4 1
1 5 10 10 5 1
1 6 15 20 15 6 1

1 9 36 84 126 126 84 36 9 1
class yanghui
{
public static void main (String args [] )
{
int i, j;
{{U}} (1) {{/U}}
int yanghui [] [];
System. out. println( “杨晖三角形：” );
yanghui = new int [ yhleve1] [];
for(i =0;i ＜ yanghui, length; i + + )
yanghui[i] = new int [i + 1];
{{U}}(2) {{/U}}
for({{U}} (3) {{/U}})
{
yanghui [i] [0] = 1;
for(j = 1 ;j ＜ yanghui[i], length - 1 ;j + + )
yanghui[i] [j] = yanghui[i - 1] [j - 1] + yanghui[i - 1] [j];
yanghui[i] [yanghui[i]. length - 1 ] = 1;
}
for ( i=0; i ＜ yanghui. length; i + + )
{
for(j =0;j ＜ yanghui[i]. length; j + + )
{{U}} (4) {{/U}}
System. out. println( );
}
}
}
【正确答案】
1、int yhleve1 = 10;
【答案解析】yanghui [0] [0] = 1;
i=1; i < yanghui, length; i + +
System. out. print ( yanghui [i] [j] +" ");
